ssl session error 0. Troubleshooting SSL connection error

SSL is a secure protocol used when visiting resources whose address begins with HTTPS. Data is transferred in encrypted form, and you don't have to worry about confidentiality. But if the certificate has expired or was not made properly, the web browser will show an SSL connection error when you try to open the site.

Causes

The failure may be caused by the server from which information about the site is requested, or by the computer running the browser. The error usually appears in browsers running on Chromium-based: Google Chrome, Yandex.Browser, Opera, Comoda Dragon.

IN Mozilla Firefox such a failure is defined as "This connection is untrusted."

If the certificate works properly, then when you click on the padlock next to the address you will see the following picture:

If an error occurs in the definition SSL protocol part of the address will be crossed out (https//), and in additional information You will read that the site's identity is not verified and the connection is encrypted using outdated technology.

This situation will repeat on all sites that you try to open.

Important: if an SSL connection error appears only on one web resource, then the cause of the failure is on the site’s side, that is, the page actually has problems with encryption.

You should use the methods below to fix a connection error only if no website that uses the HTTPS protocol can open on your computer.

Bug fix

If when opening additional information When you connect, you see a message stating that the certificate is not yet/no longer valid, then check the date on your computer. If it seriously differs from reality forward or backward, then the protocol will not work, and accordingly, an error will appear when accessing the site.

Usually the time and date are lost due to CMOS batteries. You can also replace it yourself by purchasing new source food in the store. But before you change the battery, look at what is currently installed in your system unit or laptop. If you have a battery with a wire, then you need to purchase a similar power source.

Browser check

If the date on your computer is set correctly, but the connection still fails, pay attention to the state of the browser. You must have latest version web browser. If you're using Google Chrome, go to Settings and open the About section. In other browsers, version checking is done in a similar way.

Typically, web browsers update without user interaction. But, for example, new ones are not supported on XP and Vista Chrome versions. Accordingly, when working with older operating systems, you may not be able to access some sites.

Another reason for the connection error may be the action of extensions. They will not necessarily be malicious: completely legal add-ons can also conflict with sites.

To test this hypothesis:

1. Open settings, go to the list of extensions.
2. Disable all extensions for a while, and then try to access the site again.

If the problem persists, reset your proxy settings. They may become confused due to the fact that you connected to the Internet through a proxy, or due to the actions of other applications. To reset proxy settings in Chrome:

If sites open normally in other browsers, but the connection error appears in only one browser, reset its settings. This will delete all data, but will help solve the problem.

Setting up an antivirus

Except wrong date and problems in the operation of the browser, a connection error can be caused by excessive curiosity of the antivirus and firewall. Security software checks the SSL connection. Some sites may define such a check as an attempt to interfere and block access to information.

To check whether your antivirus or firewall is to blame for the error, temporarily disable your computer's protection. This should only be done if you are confident that the site you are trying to access is secure.

If web pages open without failures when security software is disabled, configure the https scanning mode in your antivirus.

In Avast, for example, you need to go to settings, open the section " Active protection", click "Settings" and uncheck "Enable HTTPS scanning".

In Kaspersky Internet Security, the same settings are located in the “Network” section of the advanced settings.

All antiviruses have similar options, so you just need to find them and disable HTTPS checking.

There are no similar articles.

SSL- this is the name of the cryptographic protocol that ensures the security of the communication connection.

When you receive an “SSL error” while surfing the Internet, this may indeed mean that someone is accidentally or deliberately trying to obtain the data you are sending to the Internet. But it’s not always worth being afraid and trying to fix it right away. SSL error. Often, such an error can only mean incorrect browser settings, interception of connections by your own antivirus (the antivirus is mistaken for an attacker, and you shouldn’t be afraid of the data it receives), or in general there are problems not with you, but with the site you are trying to access.

If you still have the slightest doubt, it’s better to reconnect to the Internet, log in from a different browser and check if the error appears SSL connections in this case.

Let's consider possible options SSL error fixes in specific situations.

How to fix SSL error in Google Chrome and Yandex browser.

So, you are unable to access this or that site - a problem with the security certificate “pops up”. As already mentioned, there is no need to worry - first just reconnect and change the browser. If the error continues to appear, then:

• Check that the Date and Time are set correctly on your computer;
• Completely scan your computer for viruses;
• Check your antivirus settings carefully. It has already been said that it is the antivirus that a “frightened” browser can often mistake for an attacker and rush to the owner’s defense. Usually it's a matter of checking. https protocol, try to find it in your antivirus and disable it (if you don’t know where, help and searching the Internet for the name of your antivirus program will help). In general, disabling this check will have virtually no effect on the functionality of your antivirus software. If the ssl error continues to appear, try disabling the antivirus altogether for a short time (if this doesn’t help, then it’s definitely not the problem, if it helps cure it, maybe it’s worth changing the security program).
• Try updating your operating system and browser to the latest versions;
• Try creating in your operating system a new user and access sites through him;
• Try logging in from a different IP address or even a computer;
• If you cannot fix the SSL error, try combining several of the above methods at once.

If all this does not help resolve the ssl error, you can disable SSL check in the browser, but this may not be entirely secure. It’s better to study all the information about the suspicious site before doing this.

Resolving SSL errors on a tablet is a much more pressing issue than on a computer.

The fact is that, starting with Android 2.3, encryption algorithms on tablets have become noticeably weaker and the likelihood of them being decrypted by attackers (i.e. gaining access to your data) is much higher. This leads to a not very favorable situation:

• firstly, SSL errors can very easily occur where in fact there is no danger;
• secondly, on the contrary, truly experienced hackers can force the protocol to trust certificates where the danger occurs.

Basic security measures and error resolution are given above and many of them are suitable for tablets, but if you value the security of certain data, for now it is better to refrain from entering it on tablets unless absolutely necessary on suspicious sites.

Due to the increasing frequency of blocking of web resources, everything more users have to deal with access errors. However, they may not always be related to sites being blocked by providers; the problem may be hidden on the computer itself. This is an error, and it does not matter which browser is used.

The error may occur due to the lack of confirmation on the site safe work browser with this certificate site SSL , also the reason for its appearance may be related to changes in the settings software responsible for system security. Today we will look at one of the most common variants of the above error, in which the user receives a notification "Website "URL" sent an invalid response. ERR_SSL_PROTOCOL_ERROR" .

We can say with a greater degree of certainty that everything is fine with the site itself, however, you can check its availability using some service like ping-admin.ru won't hurt either. If the resource is available, you should look for the causes of the error on your computer. There may be several reasons. If the site uses a connection HTTPS first you can check if the protocols are enabled SSL2 And SSL3 in browser properties. Open the classic control panel, launch the applet.

Switch to tab "Additionally" and make sure that in the checkboxes SSL 2.0 And SSL 3.0 checkboxes are checked.

At the same time, check if it matches time on a PC with your time zone. If not, set right time and enable synchronization.

Alternatively, you can try disabling protocol filtering HTTPS , although it is undesirable to do this, since this reduces the level of security. In , for example, this can be done as follows. Go to internal address chrome://net-internals/#hsts , select from the menu on the left HSTS, in the field "Delete Domain" insert the address of the problematic site without the prefix HTTPS and press "Delete".

After this, you will be able to log into the site using the usual protocol. HTTP .

Note: Before making changes to protocol processing settings, you need to completely clear your browser cache and delete saved files cookies, and then try to access the site. If the login is completed without errors, with filtering disabled HTTPS there is no need to rush.

There is a very high probability that access to the site is blocked by something installed on your computer. antivirus software. Sometimes the cause of the error becomes obvious after enabling it in the browser private mode (incognita). Here, for example, is what it shows when going to a blocked site in incognito mode. IN in this case error "This site cannot provide secure connection» causes antivirus .

Therefore, you need to either disable real-time protection in this program, or add the blocked site to the exclusion list.

The settings of other antivirus software are checked in a similar way. In particular, users had to deal with the described error Dr.Web (firewall settings) And ESET NOD32 ("SSL/TLS protocol filtering" setting) . At the same time, you need to check the operation of the extensions installed in the browser, since some of them, in particular, SaveFrom.net may hinder normal operation With network resources. And one last thing. If you receive an access error when opening a site, use the most common anonymizer, or even better VPN -service, in most cases these tools allow you to bypass such restrictions.

“The connection is not secure” and other warning pages in Chrome... If you are a user of Chrome, Opera or any other browser based on the Chromium engine, you have probably encountered the “Connection is not secure” error when visiting websites. You go to the site, but...

Here's a typical question:

Error 107 appears when accessing https://vk.com/. When you try to log in, a message appears: “Cannot authenticate via a secure connection. Most often, this happens when the wrong software is installed on your computer. current date and time. Please check your system date and time settings and restart your browser."

Date and time are correct. Hosts file also normal. There are no viruses. Reinstalling Chrome didn't help.

Here we suggest how to fix an SSL connection error connecting to vk.com or other sites. For example, a secure connection to the server cannot be created. There could be a problem on the server, or a client authentication certificate is needed, which you do not have and is issued:

Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error.

Such VK ssl errors or yandex, google ssl errors can often occur if you do not solve some problems. Here are some guidelines to resolve the SSL error. So, if you encounter an SSL error, try these steps:

• Check if the date and time on your computer are set correctly.
• In your antivirus settings, try temporarily disabling HTTPS protocol checking
• If the problem occurs on Windows XP SP2, update it to SP3.

SSL protocol error often happens with Eset antivirus Smart Security 5, which incorrectly filters the https protocol. You need to disable https check and everything should work.

If everything is fine with SSL on the site, then most likely the problem is that Kaspersky intercepts SSL connections and then proxies them to the browser using its own crooked certificate. Normal browser it will generate an error warning about a MITM attack. You should try disabling SSL connection checking.

Often, if there is an SSL error, everyone refuses to work installed browsers. The only way out- this is to use standard IE, which in 90% of cases does not produce such an error. This browser can be used until a solution to the problem is found. In simple words An SSL error indicates that a connection to the server cannot be established for some reason.

As noted above, you need to check the settings of your antivirus, since it can block connections, which is why all the problems arise. You may need to add your browser to exceptions and set less stringent controls on incoming and outgoing traffic.

• Check your firewall settings. If necessary, lower the protection level.
• Back in Google error SSL connections can occur when you do not have an antivirus program and the system is infected. In principle, this can be solved either by reinstalling the OS or by scanning the system for infected files.
• The time settings are lost. Consequently, a discrepancy is detected on the server, and the connection is determined to be unreliable or insecure.
• An outdated browser is also a cause of SSL errors.

HTTPS is a secure Internet connection protocol that uses an encryption system to prevent data theft and decryption. The basis of secure connection in Yandex browser An SSL socket is used, which implies asymmetric cryptographic authentication for exchanging information between the server and the client. In practice, the presence of SSL is a guarantee of user security on a particular site, but not all resources provide protection due to the difficulty of obtaining a certificate.

Without availability special knowledge in security technologies, the user would not be able to determine the safety of using a resource, but with SSL it is easy to find out whether it is possible to enter confidential data or whether it is better to refrain. Yandex browser displays the presence of an SSL connection with a gray padlock in “ Smart line", by the state of the icon it is easy to visually determine the type of connection.

Important! In fact, the SSL standard is already outdated and practically not used; back in 2014, the United States announced the vulnerability of the system and obliged resources to switch to a modern secure communication protocol - TLS. It is also released by Netscape and is an ideological continuation of SSL. TLS is still conventionally called "SSL".

The lock icon will help you determine the connection type:

Why do you need SSL in Yandex browser?

The purpose of this safety standard comes down to four areas:

1. Authentication, provides identification of the user and the web server on the network. The function is important for improving the site's security system; users are able to prove their own authenticity and can verify the authenticity of a second party. Users from different parts of the world communicate via the Internet, which makes identification difficult; to avoid deception, an HTTPS connection over an SSL socket is used.
2. Guarantee of data secrecy. The cryptographic module provides a guarantee that the information will be obtained exclusively target audience(user or group, server, etc.). During data transfer there is a risk of interception, but SSL will protect against similar problems, although it does not protect 100%. The risk of interception is especially high in places with public Wi-Fi.
3. 128-bit encryption system. If all information is received by a third party, it will appear encrypted and will not be readable. The keys for decrypting data are available only on the sender and recipient sides. We cannot say that the data cannot be decrypted, since modern ASIC systems are capable of sorting through up to 50 billion combinations every second. Even with such computing power It will take days, months or even years to guess the password.
4. Creation digital signatures . Allows you to guarantee the integrity of messages and their authorship. With digital signature it is easy to prove the origin of any data; it is convincing and reliable evidence of document signing, element authenticity or user identification. The function is especially important on commercial sites and resources that perform currency transactions.

How to enable SSL in Yandex browser

The default build of the browser uses secure access on all sites that support it. If you previously changed the parameters yourself or installed a third-party assembly, the function may not work on the client side.

How to activate HTTPS/SSL support:

Not every site can be opened using an encryption system, as an error appears SSL Yandex browser. Usually the problems are easy to solve on your own.

How to fix problems with SSL in Yandex browser?

An error message often appears ERR_SSL_PROTOCOL_ERROR in the Yandex browser, it is relatively easy to fix, but there is one difficulty - the message does not provide specifics. We'll have to sort it out ourselves possible reasons failure and the appearance of unprotected access.

What could cause the problem:

1. Defeat of the system malicious code. Viruses bring the most unexpected problems, including malfunctions when surfing the Internet. Dr. will help you restore your functionality for free. Web CureIt or Kaspersky Rescue Disc.
2. Time or date error. To load a protected resource, you will need to set the correct time and date. If there are significant differences in these parameters between the server and the computer, access will be interrupted. The only exception is differences in time zones; they do not interfere with loading the site. To restore operation, set the time correctly:
3. Installed too high level security in the browser. As practice shows, excessive safety can harm the comfort of surfing. Set the appropriate security level:
   
4. The antivirus is blocking the connection. In part antivirus programs“HTTPS Scanning/Inspection” is set, which leads to periodic failures in working with secure sites. For example, in Eset NOD32 (eset internet security) the parameter is located in the “Internet Protection” - “Web Protocols” section. Disable the function and check the troubleshooting.
   

There's another one useful way Restoring access to sites - clear the certificate store.

How to clear SSL in Yandex browser?

In fact, there are three methods to help clear SSL in the Yandex browser:

1. From the network section. The fastest and easiest method to clear SSL in Yandex browser. Algorithm of actions:
   
2. Manually through a browser window. The method is interesting because it allows you to delete only individual certificates, and not their entire list.
   
3. Manually through the system. The advantage of the procedure is that we can nullify certificates simultaneously in all browsers. What to do:

Resetting the SSL storage in Yandex browser is useful when the section is cluttered or in case of errors, which often disappear if you free the section and erase some or all SSL certificates. We recommend that you always keep the section up to date (periodically erasing data) and activate HTTPS in your browser to protect the content.
