Error connecting ssl zakupki. Fixing ssl connection error. Ssl connection error - what to do

As you know, any application or program can fail one day - nothing is perfect in the world. So in the Google Chrome browser you can expect an SSL connection error. What does it mean and how to deal with it?

An SSL connection error occurs when opening a website, and such a website can be any resource, including both popular and not so popular ones. The error literally means the following: “Unable to connect to the server. The problem could be due to a server or client authentication certificate that you don't have."

This is what the error looks like in the browser:

Please note that it can occur not only in, but also in a number of other browsers that are based on Chromium: New Opera, Comodo Dragon, etc.

Problem and solution

I would like to immediately note that the reasons why this error occurs in the browser may not be related to each other. Therefore, the solution for each case will be individual. So I'll talk about a few possible solutions.

• The first step is to update your browser. Yes, the same Chrome is automatically updated, but in some cases the update can be disabled by the user. In addition, a glitch in the application itself cannot be ruled out. Therefore, click on the settings button, select “Help/About browser” and see if the current version of the browser is installed.

• Let's move on. Pay attention to the antivirus system. The fact is that it can block the SSL protocol as potentially dangerous, so it simply blocks it. In this case, you can try disabling the antivirus screens for a while and check whether the site opens in this case. In addition, in the settings of the antivirus program itself, you need to create an exception for this type of protocol.

• If you are using Windows XP SP2, you must upgrade to SP3. This solution was found on one of the forums and, according to user responses, it turned out to be very effective.

• Theoretically, the problem could be hidden in installed plugins in the browser itself. Go to settings, select “Extensions” and disable all extensions available there. If after this you were able to access the site, then the problem is in the extension and you just have to find which one is blocking the connection (disable extensions one at a time and you will find the culprit).

• Check your proxy settings. Go to your browser settings, find the “Network” subsection and click on the “Change proxy server settings” button. If a proxy server is specified in the network settings, it is possible that this is the problem. Select "Automatic detection of parameters" and go to the site.

• Alternatively, the problem may be with the site itself. But until the site owner sorts it out, you are unlikely to be able to access the site itself.

The error “err ssl protocol error” is quite common in Chrome and Yandex Browser. It may appear when you try to log into any Internet site.

What is this error

The SSL protocol allows you to make the connection between your PC and the website secure. He encrypts data connections.

Chrome, Yandex and Explorer have certain certificates for SSL (SSL) in their functionality. If the specified certificates malfunction in the browser, configuration problems arise, then the secure connection to the site is disrupted and the system displays an SSL connection error.

There are several ways to help fix the error.

Viruses

Windows can be disrupted by viruses. Accordingly, it is enough check the system one of the antiviruses. It is recommended to use Kaspersky and Dr.Web.

date and time

One possible cause of an SSL error could be an incorrect time and date. The server considers this a danger and blocks access. Just open the BIOS settings and set exact values, corresponding to a country or a specific region. Now we reboot the device, first saving the changes made.

You can also change the time in Windows - the result will be the same.

OS update

Sometimes an error may appear when outdated operating system. To correct the situation, just perform the update manually.

Antivirus problem

Quite often, antivirus programs consider the connection dangerous and can block it themselves. To do this, go to your antivirus settings and disable SSL verification andHTTPS.

Making changes to the firewall list

In some cases, the error “err ssl protocol error” may appear when working with Google services, search engines or the browser itself. In this case, you need to make changes to your personal Security Settings. You need to add the application to the list of allowed nodes.

Browser replacement

In some cases, it may turn out that the main tools to correct the situation do not work. All that remains is change browser. You can use Opera, Firefox, or any others.

QUIC

A new protocol that facilitates fast connection to the network. You can disable it in the Chrome configuration.

After opening the browser, enter the command in the address bar: “ chrome://flags/#enable-quic" You need to enter without quotes. The system itself will display: “ Quic Experimental Protocol". Click on the link and press the button: disable. After this, just restart Chrome.

Using the HTTPS protocol

This protocol is used for secure network login. It can be used to log in when an error is thrown.

In order for the site to open, all you need is a standard HTTP address add letter S to make it HTTPS. Often, such manipulations help fix the “err ssl protocol error” error.

Changing security settings

Note that in Internet Explorer the system operates in automatic mode. The settings are in effect by default.

In the control panel, open " Network and Internet". After this, you need to click: “ Internet Options". Next we go to Privacy and move the slider to middle position.

Most resources use SSL v2.0 or 3.0. Some browsers do not work with these configurations. You can change these settings accordingly. To do this you need to do the following:

Checking hosts

This tool is used to set site redirects and create routes manually. The file is located at: C:\Windows\System32\drivers\etc. Open it using notepad with administrator rights. Completely delete the contents and save.

Disabling plugins and extensions

To disable all extensions for Chrome, just press 3 buttons, which are located on the right side of the browser line. Now open " Additional settings". Now open the extensions. All plugins and extensions that are currently in use will open in the window. Opposite them there is a button that can either enable or disable use. In addition, you can immediately remove unnecessary extensions and plugins.

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

When you receive an “SSL error” while browsing 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 an SSL error right away. 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 is better to reconnect to the Internet, log in from a different browser and check if the SSL connection error appears in this case.

Let's look at possible options for fixing SSL errors 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 the problem here is checking the https protocol, try to find it in your antivirus and disable it (if you don’t know where, help and search the Internet by 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 a new user in your operating system and accessing 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 checking 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.

First, let's figure out what kind of connection this is. SSL is a cryptographic protocol that makes the connection between the browser and the resource you need more secure. Sites that use this protocol are signed as https://. You can absolutely stop worrying about information leaks if the certificate was completed in the required form and has not expired.

Method No. 1 Check the time and date settings

In your browser you may receive the message “ The server certificate is not yet valid.”, which means that the time for the certificate to work has not yet come. In this case, the problem is likely to come from you rather than from the site.

All you need to do is check the date and time on your PC. These settings are most often lost due to a dead battery on your motherboard. Just set the required time and the SSL connection error will disappear.

Method No. 2 Checking the Firewall and Antivirus settings

Sometimes the resource you go to decides that your security utilities are spyware and blocks them. To check for this problem, simply disable the check https:// in the antivirus.

Let's look at the example of an antivirus Avast how to do it go this way: Settings -> Active Protection -> Web Shield Settings

Inside this tab there is an option “ Enable HTTPS scanning” which you need to uncheck.

Method No. 3 Update the browser and system

We know that the advice to update is a rather hackneyed topic, but it is still useful advice. Update your browser and entire system. Perhaps this will solve your connection problem SLL.

Method No. 4 Malicious utilities and viruses

In the modern world, such things have incredibly huge functionality. Let's look at some of the skills of these “pests”:

• Can bypass anti-virus protection.
• Makes your PC invisible on the network to other PCs.
• They block various sites.
• They may just show you a whole bunch of ads.
• They change your start page, without your knowledge.
• Blocks port 80, etc.

Scan your PC using a special utility Anti-Malware Bytes. It will help you find various threats to your system. Even if you think you're keeping your PC squeaky clean, rest assured there's something there.

We are often asked the question: how reliable are POS terminals and what can break? As with any equipment, absolutely anything can fail in terminals; it all depends on how carefully you handle the equipment and whether you follow the operating rules. In general, terminals are designed for a long service life, but careless users significantly reduce this period.

Mechanical damage is the most common breakdown

For example, very often workers simply fill the terminals with various liquids - tea, coffee or juice, which leads to equipment failure. Here you can add various falls and throwing (yes, yes, this also happens) of terminals, as a result of which not only mechanical damage occurs, but also problems associated with the software. All of the above is not a warranty case.

Now let's look at some of the most common errors that can be seen on the screen of Ingenico POS terminals:

• LLT - the terminal is in configuration mode and is waiting for the software to load;
• SSL session error - usually occurs on POS terminals with a GPRS module. This problem is with cellular communications - to eliminate the error, you need to select a cellular operator with the most stable signal level in the place where the terminal is installed.

The following errors occur as a result of anti-hacking protection and can only be “treated” in the Ingenico Service Center:

• sad smiley - :-(;
• messages "UNAUTHORIZED", "ALERT IRRUPTION", "ERROR xxxxx" - most likely the tamper protection has worked;
• "BAD Signature" when loading LLT - the terminal is not signed, or is activated for another software vendor.

The following errors and malfunctions can be found among VeriFone POS terminals:

• The screen backlight does not light - call for service;
• DOWNLOAD NEEDED - terminal in software download mode - equipment engineers at the bank download software and configure it for the client;
• TAMPER, BAD RTC CHIP, SECURITY ALARM - if rebooting/flashing/replacing the battery did not help, call service;
• When printing a receipt, the terminal reboots - there is a possibility that replacing the power supply will help;
• The magnetic/chip reader stopped working - if rebooting/flashing did not help, contact service.

That's all for now. I hope the information was useful to you. Until next time. Good luck in your business!
