Your connection is not protected by signature algorithm. How to resolve “Your connection is not secure” in Google Chrome browser

Sometimes users Opera browser when trying to access a site using the htpps protocol, they receive the error message “Your connection is not private.” There is nothing wrong with this error, and it is very easy to fix.

But first, a few words about why this happens, and whether this error can appear in the future. The thing is that the encrypted htpps protocol is synchronized with the current time and date. And the clock on your computer, apparently, is behind, and not by a couple of minutes, but by a decent amount of time. For correct operation htpps protocol requires that packets be sent from the user's PC in the current time, and not from the past year. This is the whole point of encryption and secure access to confidential information.

Therefore, you just need to set the clock on your computer. This error may appear again in the future if the clock falls behind again. But fixing it is a matter of 1 minute.

First, ask in a search engine exact time(and date if you don't...

The browser says that the connection is not secure or the connection is untrusted

If, when you try to access the site or the server control panel, you see the following message:

“Your connection is not secure”; "This connection is untrusted";

this means that the target address has a self-signed SSL certificate installed.

A self-signed free certificate provides the same protection for transmitted data as a certified paid certificate. However, the browser will warn you that the certificate is not trusted because it has not been verified by a trusted certificate authority.

Verified paid certificates, in addition to protecting the connection, guarantee that information about the domain and its owner has been verified by an independent trusted source. If the owner of the domain is a legal entity. person, the certificate guarantees that such a company really exists, the organization’s documents are in order and the organization’s activities are legal.

On at the moment I use trial version KIS2015. stopped working after installation Google search engine in the Chrome browser. writes: "Your connection is not secure." Here full text from the page:

Your connection is not secure

Attackers may try to steal your data from the website www.google.ru (for example, passwords, messages or numbers bank cards). NET::ERR_CERT_AUTHORITY_INVALID

The www.google.ru website uses encryption to protect your information. However, the identification information we receive from www.google.ru now is different from what it typically sends. Either a malicious site is trying to impersonate www.google.ru, or the connection page to Wi-Fi networks interrupted the connection. Your information is still safe because Chrome terminated the connection before data was exchanged.

It is impossible to go to the website www.google.ru, since it uses the HSTS protocol. This could be due to a network error or an attack on the site. Most likely it will work in...

When you enter some sites, you may be in for a surprise. Google browser Chrome or Yandex Browser - error “Your connection is not secure. Attackers may try to steal your data from the site... (for example, passwords, messages or bank card numbers)." What is this error and how to solve it?

Actually, this is what the error itself looks like:

An error occurs when connecting to sites running under the HTTPS protocol. Essentially, HTTPS is the same HTTP protocol that operates over the encrypted transport mechanisms SSL and TLS. HTTPS provides protection against attacks, but only if encryption is used and the server's certificate is verified and trusted.

While surfing the Internet using Chrome browser or another that uses the same engine, you may encounter the fact that when you try to open a site somehow, a warning will appear: “Your connection is not secure and attackers may try to steal your data...”. No it's not hacker attack to your computer, it's just a certificate issue. To ensure the security of their users' data, many sites use secure protocol HTTPS, in which data is encrypted using the SSL cryptographic protocol. This is exactly what certificates are for. But this whole design does not always work correctly. Moreover, in 99% of cases, the causes of failures lie not in the server, but in the client equipment. This is what we will talk about now.

Reason one. Incorrect system time

In this case, the error code may look like this: Net::ERR_CERT_DATE_INVALID.
This all happens due to the fact that the date and time on your computer is different...

Imagine this situation. You regularly use the Google Chrome browser and everything works fine. But at one random moment, when going to some site, the site page does not load, but instead an error appears. Instead of the website you are used to, you will see the following text in your browser window: " Your connection is not secure". And under this entry there is another entry that says that attackers can steal your data.

How could such an error appear in the Google Chrome browser? In fact, there are several reasons for this. Let's look at them.

This kind of problem is related to site certificates. They may be from an unverified author or may be out of date. By the way, one of the reasons for the error “Your connection is not secure” is an incorrectly set date and time on your computer. Incorrect date and time affect certificates. For example, the expiration date of the certificates does not match the date on your computer.

The error “Your connection is not secure” may appear on some sites and this is quite normal. Since website certificates may indeed be unverified or outdated. But if an error of this nature appears on almost all sites that you open, then the situation here will be different. Here are some recommendations to help you resolve this error.

Very often an error of this kind occurs in the Google Chrome browser installed in operating system Windows XP. If you are in this case (and you have a 32-bit OS), then check for Service Pack 3 (SP3). If you have a 64-bit Windows version XP, you need to check Service Pack 2 (SP2). Both of these update packages can be downloaded from the official Microsoft website. It is located at microsoft.com.

The reason for the “Your connection is not secure” error may be your antivirus or one of the browser extensions. If the problem is related to your antivirus, then you need to disable the HTTPS protection or scanning function in it.

In order to check whether extensions are involved in this problem, you need to open the Google Chrome browser in incognito mode. First you need to disable all extensions in incognito mode. This is all done in the browser settings. Then everything is extremely simple: if the problem does not appear, then one of the extensions is to blame and, therefore, it must be removed.

Still, most often an error like “Your connection is not secure” appears when the time and date on your computer are set incorrectly. Therefore, before moving on to other ways to solve this problem, check the date and time on your computer.

Even in this popular browser How Google Chrome errors can occur. But any errors can be eliminated. An error like “Your connection is not secure” is proof of this.

When navigating to some web resources, users of the Google Chrome browser may encounter that access to the resource has been restricted, and instead of the requested page, the message “Your connection is not secure” is displayed on the screen. Today we will figure out how to fix this problem.

The developers of most web browsers make every effort to provide their users with a safe web surfing experience. In particular, if the Google Chrome browser suspects something is wrong, the message “Your connection is not secure” will be displayed on your screen.

A problem like this only means that the requested site has problems with certificates. These certificates are needed if the website uses a secure HTTPS connection, which is the vast majority of websites today.

When you go to a web resource, Google Chrome charmingly checks not only whether the site has certificates, but also their expiration dates. And if the site has an expired certificate, then, accordingly, access to the site will be limited.

How to remove the message “Your connection is not secure”?

First of all, I would like to make a reservation that every self-respecting website always has up-to-date certificates, because Only in this way can the safety of users be guaranteed. You can only troubleshoot problems with certificates if you are 100% sure of the security of the requested site.

Method 1: Set the correct date and time

Often when you go to a secure site, the “Your connection is not secure” message may appear because the date and time on your computer is incorrect.

Fixing the problem is quite simple: all you need to do is change the date and time to match the current ones. To do this, left-click on the time in the tray and in the menu that appears, click on the button "Date and Time Settings" .

It is advisable that you have the function activated automatic task date and time, then the system will be able to adjust these parameters with high accuracy. If this is not possible, set these parameters manually, but this time so that the date and time correspond to the current moment in your time zone.

Method 2: Disable blocking extensions

Various VPN extensions can easily cause some sites to not work. If you have extensions installed that, for example, allow you to access blocked sites or compress traffic, then try disabling them and check the functionality of web resources.

To disable extensions, click on the browser menu button and in the list that appears, go to “Additional tools” – “Extensions” .

A list of extensions will be displayed on the screen, where you will need to disable all add-ons that are associated with Internet connection settings.

Method 3: Outdated version of Windows

This reason for the inoperability of web resources does not apply Windows users 10, because disable it automatic installation updates are not possible.

However, if you have a lower version of the OS and have disabled automatic installation of updates, then you should definitely check for new updates. You can check for updates in the menu “Control Panel” – “Windows Update” .

Method 4: Outdated browser version or malfunction

The problem may also lie in the browser itself. First of all, you will need to check for updates for the Google Chrome browser. Since we have already talked about Google update Chrome then on this issue We won't stop.

IN lately More and more often, in the Google Chrome browser, which I use as my main one, an error appears when it is impossible to open a website, for example Avito, and a message opens with the following content: “ Your connection is not secure". It is also accompanied by a threatening comment that “Attackers may try to steal your data from the site (for example, passwords, messages or bank card numbers).”

An inexperienced computer user may have a heart ache at the thought that it could be hacked, a virus has settled on the computer, or it’s time to take it to the landfill. Of course, I’m exaggerating, but in reality, the problem exists and causes trouble when visiting the Internet every day.

Instead of readable text, an error code may also be displayed: “ERR_CERT_AUTHORITY_INVALID”, “ERR_CERT_WEAK_SIGNATURE_ALGORITM” or “ERR_CERT_COMMON_NAME_INVALID”.

The fact is that sites that require some kind of authorization in personal account, for example, social networks or online stores, are gradually moving to working using the secure SSL protocol - their distinguishing feature is that the address begins with https. If the web resource uses good old http, then the “Your connection is not secure” warning does not appear.

The reason for the problem with opening lies in an error when checking the encryption certificate that protects such resources - since they usually require you to enter some personal data, the browser considers itself smarter than you and tries to protect against possible interception of your confidential data.

At the same time this message appears only in browsers based on the Chromium core, such as Google Chrome, Yandex.Browser, Opera, Sputnik, Amigo and others.

What to do and how to still get to desired page?

To be honest, this is exactly what I do, but I can’t advise you on this, because what if the program is not mistaken and the site is really dangerous..? In addition, often this link does not exist at all.

In fact, the reason may simply be hidden in problems in the operation of the site itself. If this is the case, then the only thing left to do is close the page and return to it later when everything is fixed.

Separately, I would like to mention the occurrence of an unsecured connection error when trying to access the Internet via free wifi in the subway and in public places in general free points access - in particular, this is where I mostly encounter it. To bypass the blocking, simply enter address bar a site that definitely does not use the https protocol - for example, the address of our blog site. After this, you are guaranteed to be redirected to the online login page and you will be able to use the Internet.

But the problem may also be in the browser or system settings, and since we cannot know for sure whether the site or the computer is to blame, we will try to take several steps that can help cope with the problem.

Your connection is not secure in Chrome

First of all, you need to determine whether the site does not work on only one browser, or on all. Surely you have a built-in Internet Explorer or its newer brother Microsoft Edge, built in by default Windows system. Open the site in it - if it works, then just clear the cache and cookies in the browser in which the page does not open.

To do this in Google Chrome, go to the settings menu, section “History”.

In the window that appears, put a tick on

• Cookies and other site data
• Images and other files saved in cache

And in the drop-down list, select the period “All time”, and then click on the “Delete data” button

To be sure, you can also disable extensions (additional browser plugins) - they can also interfere normal functioning. To do this, also go to the menu under the heading “Additional tools - Extensions”

And remove all the checkmarks from installed extensions

If you have a different browser, then clearing cookies and cache is similar to the described algorithm. You can also use one of the many cleaning programs to do this. system garbage, for example CCleaner, Wise Registry Cleaner or any other.

If all this does not help, as a last resort, try uninstalling the entire browser and reinstalling it.

Pages do not open on all browsers

If the message “Your connection is not secure” appears on absolutely any browser, then the reasons, as you understand, lie in the system itself and there may be several of them - let’s look at the main ones.
