• Skype mac connection failed. Why is there no connection on Skype? Detailed analysis

    While working with Skype, a message often appears stating that a connection cannot be established. Appearing at the wrong moment, the message breaks the connection, preventing you from finishing the conversation. Getting Skype back to work is easy. You need to understand the causes of the problem and perform a sequence of actions.

    Reasons for the error

    After entering your login and password, this data is sent to the server for verification. After confirming the data, the server informs the program on the computer that the data is reliable and authentication has been completed. If a connection error occurs, this means that the program cannot synchronize with the server and does not allow the user to access the network.

    Among the reasons for the lack of connection are the following:

    1. The version is outdated and no longer relevant.
    2. The program is blocked by the Windows Firewall.
    3. The computer is not connected to the network.
    4. The provider has blocked Skype.
    5. The program server is not responding.
    6. The program has crashed.

    Troubleshooting

    I will analyze cases in which a malfunction occurs in Skype.

    Checking your Internet connection

    The first thing to do if Skype is unable to establish a connection is to check your network connections. Launch any browser and try to access any website. If there is no Internet, we see a corresponding message.

    Checking the program version

    Microsoft regularly releases updates for its product. The company is interested in ensuring that users use only new versions of the product. Therefore, older versions are unstable and often crash. Information about the current version is available in the “Help” section. In the pop-up window, click About Skype.

    In addition to the version, the manufacturer indicates the year the update was released. Versions released last year are considered out of date.

    The update is made through the official website. Go to Skype.com and click “Download”.

    Disabling the firewall

    Another reason why Skype says “Connection could not be established” is because Windows is blocked. Firewall is a standard protection that is present in all versions of Windows. It blocks suspicious activity from the network. A firewall is a useful application, but its operation also affects the stability of useful programs and applications. In particular, it can cause problems with Skype. To check the influence:


    Disabling antivirus

    It has a list of programs that it blocks or prohibits access to the Internet through them. Skype sometimes falls into their number. If this happens, add the program to the antivirus exclusion list, and network access will be restored.

    Router settings

    Skype malfunctions are caused by improper operation of the router. To eliminate this possibility, do the following.

    Skype is one of the most popular programs for communicating people via the Internet. It is used by millions of people almost every day, connecting with their relatives, friends, work colleagues, business partners and so on. Everyone knows that no program is thorough, so such a “monster” can also have glitches, that is, the service automatically generates errors. The most common error that Skype gives is that the connection could not be established.

    What is the reason for such problems? As practice shows, there may be a lot of problems and factors due to which the Skype connection could not be established. Some of the problems are minor, so they can be easily fixed, others require setting up the service, which will also not take much time.

    Unsuccessful deletion

    Quite often there are cases when, after removing old versions, the program is not completely removed, so files remain on the computer that cause such connection failures. What to do in this case? The answer is quite simple - you need to remove old versions of the messenger from the computer’s memory, and also make sure that the work was completed successfully and all program files were deleted.

    The second point is that the version you downloaded must be suitable for your computer’s operating system. After all, mistakes often happen only because of this factor. That is, after installation, the version of the messenger does not “work” with the operating system of the computer device, so Skype cannot establish a connection. There is only one solution to this issue - carefully select the version of Skype, this will help you quickly install the program and use it in the future without problems.

    Firewall Settings

    It is advisable to check your firewall settings, because it is because of this that Skype very often gives a connection error. If your device operates from a router signal, then you need to check its connection.

    You also need to check the settings of the router, as there may be a mode for blocking applications or a setting “ parental controls" Very often, “parental controls” are installed when PC users do not have experience in working with the device, so they can make incorrect settings, as a result, all applications are strictly blocked.

    To establish a Skype connection, all these settings must be removed.

    If the router is not used. There may be a problem with the firewall. However, you need to remember that the firewall may be built-in or located in other programs, such as antivirus programs. Therefore, to check the connection, it is advisable to temporarily disable your antivirus program. This work will only take a few minutes, so you will not have time to catch the virus, but you will find out whether the firewall is causing the program to fail. If you realize that this is not the case, then you need to check the operation of the built-in Windows firewall, especially for Windows 7, which often causes such problems.

    It needs to be disabled, which can be done in the settings. To disable the Windows Firewall, go to the Control Panel, then to the Security System and disable this application. And if this was the only reason, then you will be able to use the application immediately.

    Internet Explorer

    The next common reason when there is no download server is Internet Explorer. At first glance, this may not be the case, but sometimes this program can also cause a lack of connection. The main reason lies in older versions of the browser, in which the installation content becomes corrupted, causing Skype to display an error. Solving this problem is quite simple, there are only two ways:

    • install Skype version 6.14 and higher;
    • install the latest version of the browser.

    Communication program settings

    If you have the Internet, and all the settings have already been revised, then there is one more option why Skype is writing an error, these are incorrect settings of the communication program itself. The user may have specified an incorrect communication port or something else. There may also be connection errors if there is a problem in the hardware department of the computer. That is, the microphone or video camera could break, or the user could install the drivers incorrectly. After all, early versions do not always make contact with later ones, so there are software-level conflicts. Another very common problem of failures is the overload of “supernodes”, that is, the directory that the user accesses when dialing is clogged. And if there are a lot of calls to one node at once, then there may be no connection.

    Based on this, you can see that the error when connecting to Skype is insignificant and can be easily solved. Therefore, if you encounter this problem, there is no need to be upset. Everything can be solved in a few minutes on your own, without resorting to the services of specialists.

    Internet messenger Skype is the most popular program for users to communicate online. With its help, you can make voice and audio calls, exchange text messages and files, organize online conferences and even call landline and mobile phone numbers. The main advantages of this program are that it is free, simple and has a high level of security.

    But even such a reliable and high-quality tool as Skype cannot guarantee that at some point its operation will not fail. Problems with the messenger are not such a common occurrence, but they still occur. One of the most common is network connection failure. The error that appears is that when logging into Skype, it says that the connection could not be established.

    The causes of the problem can be different, related both to global network settings and to the program itself, which happens much more often. At the same time, Skype usually does not connect to the Internet, although there is Internet, and other programs that use it connect perfectly to it. Let's figure out why Skype sometimes writes “The connection could not be established,” and what can and should be done to restore its normal operation. We will move from simple to complex.

    Temporary unavailability of the service

    It's unlikely, but it could be that your ISP, network administrator (on corporate computers), or even your own firewall is blocking access to Skype domains. Then it is not surprising that the user cannot log into Skype. To exclude this possibility, go through Internet Explorer (!) to the page www.skaip.su/proverit-dostup-k-skaypu and click the "Check" button. The status of all servers should be “Connection successfully established”.

    If a connection could not be established for at least one of the servers, this will indicate one of the three reasons listed above.

    If everything is in order with the firewall (how to check it below) and Skype still cannot establish a connection, contact your system administrator or your Internet provider's support service for help. We also recommend checking the functionality of the Skype servers themselves on the page www.skaip.su/status-serverov-skayp. The servers must have the “Working” status, otherwise you need to wait until the technicians themselves fix the problems.

    Outdated version of Skype

    By default, Skype is updated automatically and this is important, since the correct operation of the messenger on the local computer directly depends on server services.

    If you are using an older version, at one point the program will not be able to connect to the remote host, and you will receive the error described above. It is not difficult to determine the version you are using; you just need to select it in the main menu Help - About Skype.

    There you can also check the availability of a new version of the application.

    If your messenger is out of date, go to the official website of the developer and download the current version. Close the broken program and run the web installer. The latest version will be downloaded to the PC and installed immediately, while the old version will be deleted. If installation problems occur, it is recommended to completely uninstall Skype, including the user directory %userprofile%/AppData/Roaming/Skype, and then clean the registry with CCleaner or another similar tool.

    Note: Skype folder, more precisely the main.db file in the directory AppData/Username, contains correspondence history. If you don’t want to lose it, create a backup copy just in case, and in general, first try limiting yourself to deleting the shared.lck and shared.xml files.

    Outdated version of Internet Explorer

    Since Skype desktop uses MSIE components, the connection error may be related to the Internet Explorer browser. It is noted that in some cases Skype does not work and says “check your Internet connection” in Windows with the sixth and seventh versions of IE. For a successful connection, at least the eighth version of the standard browser must be installed on the system. Please update your built-in browser to version 8 or the latest version available for your OS.

    Resetting IE settings won't hurt either. To do this, open its properties (via the classic control panel or by pressing Alt and selecting Tools – Browser Options).

    Next, switch to the “Advanced” tab in the window that opens and click “Reset.” Before resetting, we recommend checking whether the SSL 2.0, SSL 3.0, TLS 1.1, TLS 1.2, TLS 1.0 checkboxes are checked in the same tab. If not, install the birds, restart the browser and check the operation of Skype.

    Blocking by firewall or antivirus

    If you are using a built-in or third-party firewall, try disabling it for a while.

    Restoring the connection will indicate that Skype is blocked by a firewall. Disabling this protection completely for the sake of Skype alone is not the best idea, but you can create a separate rule for the messenger that allows incoming and outgoing connections. You should also check whether Skype is accessible in the settings for allowing interactions between applications and components.

    At the same time, it’s worth checking your antivirus’s “loyalty” to Skype and, if necessary, adding the application to its white list.

    Action of viruses and modification of the HOSTS file

    The cause of the problem may be a common virus that has overwritten the contents of the HOSTS file. Carefully scan the system with an anti-virus program, check if there are any “rogue” servers in the specified file. The HOSTS file is located at C:/Windows/System32/drivers/etc, you can open the file itself with any text editor.

    By default, the contents of this file should look like the one shown in the screenshot.

    If there are any addresses listed below, delete them.

    Ports and proxies

    If you use IP address spoofing programs on your PC, temporarily disable them or create (if the appropriate option is available) an exception. Users who have previously configured a messenger connection through a proxy should check the validity of the IP address and port. Skype will not work and the connection will not be established if the port is blocked or has low bandwidth. We remind you that proxy settings can be changed on the “Connection” tab in the application’s advanced settings.

    For the messenger to work correctly, ports 80, 443, 3478-3481 UPD and 49152-65535 UPD+TCP must be open on the computer. Check them in any online port scanner, for example, 2ip.ru/check-port and, if any of these ports are closed, open it by creating a separate firewall rule for it or a group.

    Interestingly, some users reported that the connection was restored when they unchecked the boxes that allowed the use of ports 80, 443 and the upnp protocol. Try this option too.

    Router settings

    Incorrect router configuration is another reason why the “Connection could not be established” message appears in Skype. The ports may be blocked on the network device itself. To enter the router settings, go to the browser at 192.168.0.1 or 192.168.1.1, the default login and password are admin/admin. In most routers, the subsection you need is called “Virtual Servers,” but there may be another name. For example, in D-Link it is “Firewall”.

    Virtual servers or VPS are a special service that simulates the operation of a real physical server. On a separate computer, it provides complete and independent control over the local network and can be used to set various restrictions, for example, parental controls. In theory, the “Virtual Servers” subsection should be empty. If there are already settings there, try to find out who made them and for what purpose. Perhaps you yourself ordered this service from your provider and forgot about it.

    Pay attention to the “External port (end)” parameter. Let's say it's 49650.

    So, this value must be specified in the additional Skype settings on the “Connection” tab, namely “Use port [number] for incoming connections.”

    If the “Virtual Servers” subsection is empty, you can create your own VPS to resolve the Skype connection error. In this case, we take the values ​​for the start and end external ports from the range 3478-3481 UPD and 49152-65535 UPD+TCP. Select the appropriate protocol.

    Perhaps this will be interesting

    Above, we looked at the main causes of problems and learned what to do if Skype writes “The connection could not be established.” Most of the tips offered concerned the desktop and portable versions of the messenger, but this program also has a web version that can be used in IE, Chrome and Firefox. It is available at web.skype.com. In general, the web version duplicates the functions of the desktop version, but for it to work correctly you need to install a plug-in. You will be prompted to install it when making your first incoming or outgoing call. If you have Windows 8.1 or 10, do not forget about the universal version of the messenger.

    Skype is a very popular program, which in 2018 is already experiencing its tenth resurrection. A large number of updates and innovations allowed it to become in demand again. The developers were able to solve most of the problems, but you can still often see a message on your screen: “Skype - the connection could not be established.” This problem is solved in a few minutes in most cases. This material presents the most common solutions; any user of a personal computer can perform them.

    Possible reasons

    To understand the cause of this problem, you need to understand what processes occur before it. When the user enters his username and password, the utility processes the information and passes it through the official server.

    The accuracy and presence of such a profile is checked, and then a response message is sent, which should confirm authorization. The error means the following: Skype cannot receive a response from the server, so it does not connect the user.

    Several possible reasons for the problems encountered :

    1. Skype must be constantly updated. If the auto-update service is turned off, then your program simply becomes outdated. Over time, this will cause a lot of problems. If you cannot establish a connection, then this option may be the reason - your version is too old.
    2. The firewall simply blocked Skype. Another popular option is when Windows has blocked access to the utility.
    3. No internet connection. Yes, many users simply do not check whether there is access to the network at the moment and only realize it after half an hour. Sometimes the cause may be incorrect router settings.
    4. Your Internet provider may simply prohibit the use of Skype. This option is quite rare, but it does happen.
    5. The program received critical damage and stopped working correctly. If there are constant power fluctuations in your area and the computer turns off, or there are a lot of viruses on the PC, all this can cause a breakdown.
    6. The official server is unavailable at the moment. Often, technical work is simply carried out on it.

    6 Basic Methods to Fix the Problem

    So, we have listed the most common causes of this problem. If the program cannot establish a connection, then you simply will not be able to start using it. This fact prevents her decision from simply being put aside and forgotten. After all, Skype is used for work and other important things. We will list the six most basic options that will help you enable the utility.

    Method 1: Check the network connection

    Let's start with the simplest method. You should check if there is an Internet connection. In most cases, users do this even before directly searching for solutions on the Internet. But still, look at the start menu, at the bottom left of the screen. If there is a connection, but you cannot access any page on the Internet, then the problem is a bad connection. There may be problems with your router.

    Lack of Internet connection prevents the program from sending data to the server and receiving a response. Therefore, it must not only exist, but also have a good connection.

    Method 2: The program version is out of date

    As we already wrote, perhaps your version of Skype is simply too old. This problem is solved by checking a box in the settings, which allows the utility to update automatically. But users very often turn it off so that Skype does not take away traffic or for other reasons. Then they forget about it and, as a result, the version of the utility on the personal computer is too old.

    First, you need to find out about your current version of Skype. This is easy to do - go into the program, and then go to the toolbar. Now click on the words “Help” or “***” and on the next column where it says “About Skype”.

    A special menu will appear in front of us, in which there will be a line with the program version. It is highlighted with a green line.

    The process can be speeded up if you find the version creation date, it is underlined in red. If the year is the same as now, then it is definitely not outdated.

    If your version is outdated, you need to update it. To avoid problems, it is better to immediately uninstall the old version of the program and install the new one.

    To do this:

    Open the Start menu on the desktop and go to the control panel. Now you need to go to the uninstall programs item

    • The old version of Skype is no longer available on your personal computer. We open the official website of the utility; it can be easily found on the Internet using simple search engines.

    • Next, open the installation file and follow all the instructions.
    • Done, you now have the latest version of Skype on your computer.

    The utility does not have to be uninstalled; when installed from the official website, the old version should “recycle itself” itself. But sometimes this does not happen and a conflict may begin, so it is better to play it safe.

    Reinstalling the program does not guarantee that you will solve the problem. If nothing has changed, then the problem is somewhere else. It is also worth remembering that there are the most popular versions that work best. When talking about Skype, one cannot fail to mention 7.14.0.106. This version is considered the most stable and has virtually no problems. Therefore, we recommend installing it if the update does not solve anything.

    Method 3: Disable the firewall

    All modern versions of Windows have a firewall, it is built in automatically, you do not need to download it. It so happens that this program very often becomes the cause of many problems. It blocks access to other utilities, blocking their capabilities and functions. Fortunately, there is a solution.

    You can simply disable it, but to do this you need to carry out a small series of actions:

    • Now you need to try to launch Skype again. If it was blocked by a firewall, it will immediately connect to your account. If the problem is not there, then you will again see a window - the connection could not be established.

    If the reason was hidden in the firewall, then we advise you to turn it on again, and simply add Skype to the exceptions. This is an easy procedure that is performed within the program.

    Method 4: Disable the antivirus

    Many people believe that antiviruses are more trouble than they're worth. And this is true, because you have to pay for good protection. Any, even the most insignificant, file can raise suspicions in your antivirus. In this case, he will simply throw it into quarantine, and in the worst case scenario, delete it. It is for this reason that many programs simply stop working, because the antivirus blocks their capabilities, considering them dangerous.

    If you don't have an antivirus at all, then just skip this method. Otherwise, open your “protector” right now. The problem is that there are no specific instructions, because all antiviruses are different.

    In any case, you need to go into the settings of this program and look for the following names:

    • Quarantine
    • Parental Controls
    • Blocked
    • Under treatment

    Often this is where you can find the Skype file. You will understand that this is it by the name that should be in the element. There are several solutions below. You can remove a file from quarantine and then add it to exceptions. Then the program will be able to work constantly, even with the antivirus enabled. But first, we advise you to check whether this is the problem. To do this, turn it off and then try to log into Skype.

    If the problem is in the antivirus, then go to the settings and find the “Exceptions” line. Find the blocked file in your Skype folder and add it to the list.

    Almost every modern antivirus is the same in terms of settings. Therefore, these processes should not cause you problems. The picture below shows how this is done in Kaspersky Internet Security.

    If you don’t need an antivirus as such, you can simply remove it. But we do not recommend doing this, because your computer simply needs some kind of protection. Ultimately, it's up to you to decide. First, check whether the Skype problem is related to the antivirus or not.

    Method 5: Setting up a router

    If you see a connection error on the screen, then the problem may be with the router. This device allows you to use the Internet. If it starts to work incorrectly, then it is very easy to check - the network simply will not exist on your personal computer.

    The second option is that the router settings are incorrect. To go into the router settings, you need to use your browser.

    Now let's go in order. As you already understood, you need to open your browser.

    1. The router settings may look different, it all depends on the model of your equipment. But in any case, we need to enter a username and password. In this regard, despite the visual differences, all settings are the same. In both lines you need to enter the word – admin and click “Login”.
    2. Now we look for the item with virtual servers in the window that opens. In different settings, this line can be located here and there. But it won’t be difficult to find it, click on it.
    3. A new window opens in front of us, in which we look for the “Add” item and click on it. We will be asked to fill out a couple of fields. We advise you to write simply Skype in “Name” so as not to get lost in the future. In the “Port” field, enter a set of numbers, for example, 5417. Now you need to click on the “Save” button and exit this window.
    4. Next, open our Skype and go to settings. We need a line with tools, which is located at the top. There we find and click on “Connection problem”.
    5. There you will also find the line “Use port”. Now we need the numbers that we entered in the router settings. We enter them and save, restart the utility and try to log in again.

    If it doesn't work, then the problem is not with the router. And remember that the settings always differ depending on the model of equipment. Therefore, we have provided approximate names. Sometimes to save the created port in the router settings you need to click “Save”, in other cases “Change”. A port can become an internal port, everything is individual, but the meaning remains the same, so it will be easy to understand.

    What to do in this case? Why can this even happen? Answering these questions is not so easy. Especially considering that the application most often fails on computers. Nevertheless, today we will learn how to deal with the problem under study. So what should you pay attention to first?

    Internet connection

    Skype failed to connect? What to do? The first thing you need to do is check that you have a network connection. Its absence leads to the appearance of the mentioned message.

    In general, this alert indicates that Skype cannot connect to the application server. The program sends a signal, but does not reach the server. Accordingly, it is impossible to work with the application.

    To check, you can open your browser and try to access any website. Didn't work out? This means there is something wrong with the Internet! This was the reason for the failure.

    Problems with your Skype Internet connection may be caused by:

    • debt to pay for network access;
    • failure of the provider;
    • accidents and technical work on transmission lines;
    • OS crashes.

    You can try to restart the Internet and modem. As soon as network access is restored, an error like “Skype cannot establish a connection” will not appear.

    Old versions

    The next scenario is that the user has an outdated version of Skype. Such applications are no longer supported by developers over time.

    Got the message "Skype could not connect"? What to do? Now is the time to look at the software version and update it if necessary.

    To do this you will need:

    1. Open the Skype authorization window.
    2. Go to "Help" - "About Skype".
    3. Look at the application version and the year the build was created.
    4. If necessary, open skype.com and download the latest version of the application from there.
    5. Install Skype and try to connect again.

    Important: it is better to remove the old version of the software. To do this, it is recommended to open "Start" - "Control Panel" - "Add or Remove Programs" - "Uninstall...".

    Firewall

    But these are not all the options for the development of events. Skype does not have an Internet connection sometimes due to the built-in firewall. It appeared in Windows with the Windows 7 version. To correct the situation and log into Skype, the mentioned service will have to be disabled.

    To do this you will need:

    1. Go to "Control Panel". The corresponding item is located in the start menu on the left side of the screen.
    2. In the "View" section, set "Category".
    3. Select "System and Security".
    4. Click on "Windows Firewall".
    5. In the left menu, click on "Turn firewall on or off."
    6. Set "Disable" everywhere.
    7. Click on "Save/Ok".

    Now you can try to launch Skype again. If the problem is the firewall, then the application will start working at full capacity. Still, a notification appears on the screen: What should I do next?

    Antivirus

    It is possible that the installed antivirus is interfering with the application. It’s not for nothing that developers recommend turning off this software when initializing programs and when launching some utilities. Maybe Skype files are recognized as malicious for one reason or another.

    How exactly to disable the antivirus? It all depends on what PC security application a person has installed. Most often, just right-click on the software icon in the Windows tray and select “Exit” there.

    Equipment

    Sometimes it is impossible to establish a connection in Skype due to the modem/router. For example, if it fails or a settings reset occurs. Unfortunately, users forget about this point.

    More precisely, the following instructions will help:

    1. In the browser, type 192.168.0.1. The number may change. It can be clarified in the router documents.
    2. Log in to the system. Usually the default password and login is admin.
    3. Go to "Virtual Servers".
    4. Click on the "Add" button.
    5. In the "Name" section write Skype, in the "Port" (final) - 4960, for example.
    6. Click on "Save".
    7. Open Skype.
    8. Go to "Tools" - "Connection problems...".
    9. Specify the port specified in the router settings in the "Use Port" window.
    10. Click on "Save".

    Resetting Skype settings

    Skype failed to connect? What to do in this case? The last tip is to reset the application settings.

    How to bring your idea to life? You will have to:

    1. Open "Start".
    2. Type %appdata% into the search bar.
    3. Login to the mentioned folder.
    4. Open the Skype section.
    5. Select all documents and delete them.
    6. Launch Skype and log in using your username.

    All of the above methods turn out to be quite effective in practice. But you shouldn't dwell on them.

    Extreme measures

    Skype has no internet connection? Didn't all the proposed methods solve your problems? Under such circumstances, you can act differently.

    How exactly? You should try:

    1. Perform a complete reinstallation of the program.
    2. Roll back the operating system to a time when Skype was working normally.
    3. Check your computer for viruses, remove the computer infection and log into the messenger.

    The most radical way is considered to be a complete reinstallation of the OS and formatting the hard drive. Fortunately, this technique is rarely needed. Can't connect in Skype? From now on it is clear how to act in the event of such an error. She's not as dangerous as she seems. The main thing is to understand why the failure occurred. This is not always easy to do!
