What is ssl protocol error. How to fix SSL connection error? Malware, viruses and other "evil spirits"

SSL is a secure protocol used when visiting resources whose URL starts with HTTPS. Data is transmitted encrypted, so you don't have to worry about confidentiality. But if the certificate has expired or is improperly manufactured, the web browser will show an SSL connection error when trying to open the site.

Causes of occurrence

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

Mozilla Firefox detects this failure as "This connection is not trusted."

If the certificate works as expected, then when you click on the lock next to the address, you will see the following picture:

If an error appears in the definition of the SSL protocol, part of the address will be crossed out (https //), and in the additional information you will read that the site's identification data has not been verified, the connection is encrypted using outdated technologies.

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

Important: if an SSL connection error appears only on one web resource, then the reason for the failure is on the site side, that is, the page has real encryption problems.

You should only use the following methods to fix a connection error if no HTTPS sites are opening on your computer.

Bug fix

If, when you open additional connection information, you see a message that the certificate is / is not yet valid, then check the date on your computer. If it is seriously different from reality forward or backward, then the protocol will not work, respectively, an error will appear when accessing the site.

Usually the time and date get lost due to a dead CMOS battery. You can also replace it yourself by purchasing a new power supply from the store. But before changing the battery, see which one is currently installed in the system unit or laptop. If you have a battery with wiring, then you need to purchase a similar power source.

Browser check

If the date on the computer is set correctly, but a connection failure still appears, pay attention to the state of the browser. You must have the latest version of your web browser. If you are using Google Chrome, go to the settings and open the "About" section. In other browsers, the version check is similar.

Typically, web browsers are updated without user intervention. But, for example, newer versions of Chrome are not supported on XP and Vista. Accordingly, when working with old operating systems, you may not get to some sites.

Another reason for a connection error can be the action of extensions. They don't have to be malicious: legitimate add-ons can also conflict with websites.

To test this hypothesis:

1. Open the 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 get confused due to the fact that you connected to the Internet through a proxy, or due to the action of other applications. To reset proxy settings in Chrome:

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

Configuring antivirus

In addition to the wrong date and problems with the browser, the connection error can cause excessive curiosity of the antivirus and firewall. The 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 if the antivirus or firewall is to blame for the error, disable the protection of your computer for a while. This should only be done if you are confident in the safety of the site you are trying to access.

If web pages open without interruptions when the security software is disabled, configure the https scan mode in the antivirus.

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

Usually ERR_SSL_PROTOCOL_ERROR you can only see in Google Chrome browser. Often this error occurs when trying to visit popular sites, for example: Youtube, Facebook and others, but the connection to other sites occurs without error. I know you are wondering why this error appeared on my computer or phone. By the way, this error can also appear on a smartphone if you use the Chrome browser or the like.

In this article, I will describe this error, then I'm going to highlight a few of the causes of it, and finally, show a few working solutions that you can try.

What are "SSL" and "SSL Connection Error"?

First of all SSL this is an abbreviated form Secure Socket Layer and it is the protocol used on the Internet to create a secure and encrypted connection between you and the server of the website to which you are connecting. Thus, SSL guarantees secure data transmission.

Usually all recent versions of web browsers such as Google Chrome or Internet Explore having some pre-saved built-in certificates for SSL connection. When these certificates are broken or your browser has configuration problems, it can cause a problem connecting to a site whose server is using an SSL connection.

All reasons for this error with SSL:

There are usually so many different factors that can cause this error, I have tried to list them all in the following list:

• Date and time of mobile phone or computer are incorrect.
• Certificate names conflict with each other.
• SSL certificate of the site to which you are connecting not trustworthy.
• Connection problem between your computer and the internet.
• A firewall is preventing you from accessing the website.
• The web page you are trying to open contains unsafe content.
• There are some issues with your computer's operating system.
• Your browser has some configuration issues.
• The antivirus installed on your computer prevents you from connecting to the site.

Let's get down to solutions or how to fix err ssl protocol error google chrome ?:

Try restarting your computer or phone first. During reboot, the operating system performs several types of background diagnostics.

Solution # 1 is the correct date and time.

If the date or time is not set correctly on your computer or phone, then this error most likely occurs for this reason.

You just need to rearrange the date, time and region to the correct values. On different operating systems, the time is set differently. I think you can easily find this feature in the settings.

Solution # 2 - Change QUIC settings

Solution works for Windows, Mac and Android:

QUIC Is a new experimental protocol that is needed to quickly connect to the Internet. The main job of this protocol is to support multiple connections. You can disable this setting Quic in your browser config Chrome.

The shutdown process is the same for all Windows, Mac and Android devices, just follow the instructions:

Solution # 3 - Using Https

Solution works for Windows, Mac and Android:

HTTPS it is a protocol for secure communication over a network that is commonly used on the Internet. So you can also try to open the website by changing it Url under the protocol HTTPS.

Try typing in the address bar https: //www.facebook.com instead of using http: //www.facebook.com (Facebook URL was used for example)

Solution # 4 - Change security settings.

You can try changing your Internet security settings. Perhaps they are the ones who block access to the site. And so what needs to be done:

Solution # 5 - Change your firewall setting

The solution only works for Windows (sometimes on Mac too):

In some cases, a firewall is blocking the internet connection. Disabling the firewall might fix the problem.

I will show you the process of disabling the firewall just for Windows but not for Mac or Linux. In fact, only Windows has this internet connection firewall issue.

Decision No. 6 - Change SSL Setting support or err ssl protocol error ssl protocol error.

Solution works for Windows only:

Most websites use SSL v2.0 or 3.0. By default, the browser does not use SSL 2.0 and SSL 3.0... Thus, we can change the default browser settings to fix the error. Follow the instructions below to complete this procedure.

Solution # 7 - Reset SSL state

Solution works for Windows only:

It usually takes a while to create an SSL connection, which is why it keeps the cache itself to prevent it from going through this procedure every time it connects to the server. This is done for faster connection and time savings.

Basically, manually clearing the SSL cache doesn't need to be done day in and day out. This is done when any connection errors occur.

Thus, to clear the SSL cache:

• Go to Internet settings from the control panel Windows and click on the tab Content.
• After that you will find the name of the parameter " Clear SSL», Just click on this button.

Problems sometimes arise in the work of any browser. Opera is no exception, which may experience an SSL error. Before we deal with its elimination, let's see why it appears.

Reasons for the error

In most cases, an ssl opera error indicates that there is a problem with the system. This problem usually indicates that the connection to the server cannot be established. Often the error can be easily resolved. It can be caused by antivirus software or firewall software. They can block the connection, which will prevent it from establishing. In this case, the error will occur not only in Opera, but also in other Internet browsers, for example, also in Google Chrome. You will learn more about the causes of this error in Google Chrome and how to solve this problem.

In addition, the problem appears in the opposite case, for example, when a computer is infected. In such a situation, you just need to install an antivirus and scan the system. Also, the reasons for the error may be a failure in the time settings or an outdated version of the browser, so it will be useful.

Attention! Often an SSL error is thrown when you want to visit a site with an expired or unreliable certificate. In principle, you can go to the resource, however, such a step entails the possibility of infecting the computer with malware.

Remedies

After the problem has been diagnosed, you should see how to get rid of it. So, how to fix the ssl opera error is a fairly common question for novice users. If the problem occurs due to antivirus software, then to check it, disable it and restart your browser. In the event that everything is in order, you will need to change the antivirus settings. They are different in each program, but the main thing to do is add the Internet browser to the exceptions and reduce control over inbound and outbound traffic. In the firewall, you will also need to make a lower level of protection.

A common cause of an SSL error is a lost date on the computer. In order to fix this, you need to click on the date in the tray and set the correct one. Now let's look at what needs to be done directly in the browser. The SSL error can be corrected by going to the Cookies section and checking the box next to the option to keep local data. In addition, we do the following. Open Opera and go to the main menu.

1. After that, select the Settings item.
2. In the window that opens, go to the Advanced section.
3. On the left side of the window, select Security from the list.
4. Click the Security Protocols button.
5. We put a selection next to Enable SSL
6. Click OK and restart the browser.

In Windows XP SP2, a similar problem can also occur. In this case, you can get rid of it if you upgrade to SP3. It is also necessary to add that, which will reduce the risk of an error. It is also worth running a scan of the system for viruses from time to time.

As you can see, the SSL error in Opera, like in other browsers, is usually easy to fix. The main thing is to find the reason why it appeared. This can be either a failure in the date on the computer, or a change in the browser settings. In some cases, the easiest way is to set the default options and check if the error persists. If it still appears, then you need to disable the antivirus, because often it is he who blocks the connection to a particular site. In rare cases, the error appears due to a computer infection with malware. In such a situation, it will be necessary to check the files, and delete or quarantine the infected.

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, the terminals are designed for a long service life, but sloppy users significantly reduce this period.

Mechanical damage - the most frequent breakdowns

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 throws (yes, yes, it happens) of the 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 - terminal is in configuration mode and is waiting for software download;
• SSL session error - usually occurs on POS terminals with a GPRS module. This is a problem with cellular communications - in order to eliminate the error, you need to choose 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-burglary protection and are "treated" only in the Ingenico SC:

• sad smile - :-(;
• messages "UNAUTHORIZED", "ALERT IRRUPTION", "ERROR ххххх" - the anti-tamper protection was most likely triggered;
• "BAD Signature" when loading LLT - the terminal is not signed or activated for another software vendor.

Among the VeriFone POS terminals, you can find the following errors and malfunctions:

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

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

SSL is the name of the cryptographic protocol, which ensures the security of the communication connection.

When an "SSL error" is issued while working on the Internet, it really can mean that someone is accidentally or deliberately trying to get the data you are sending to the Network. But you shouldn't always be afraid and try to fix an SSL error right away. Often, such an error can only mean incorrect browser settings, interception of connections by your own antivirus (antivirus is mistaken for an attacker, and you should not be afraid of the data it receives), or in general, the problem is 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, go from another browser and check if an SSL connection error appears in this case.

Let's consider the possible options for fixing the SSL error in specific situations.

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

So, you can't go to this or that site - a problem with the security certificate "pops up". As already mentioned, don't worry - just reconnect and change your browser first. If the error continues to appear, then:

Check if the Date and Time are set correctly on the 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 intruder, and rush to the owner for protection. Usually the point here is to check the https protocol, try to find it in your antivirus and disable it (if you don't know where - help and search on the Internet by the name of your antivirus program to help). In general, disabling this check will practically not affect the functionality of the anti-virus software. If the ssl error continues to appear, try briefly disabling the antivirus altogether (if that did not help, then the problem is definitely not in it, if it helped to cure it, it might be worth changing the security program). Try to update your operating system and browser versions to the latest; Try to create a new user in your operating system and go to sites through it; Try to log in from a different IP address or even a computer; If you can't fix the SSL error, try combining several of the above methods at once.

If all this does not help to resolve the ssl error, you can disable SSL verification in the browser, but this may not be entirely secure. Better before that, study all the information about the suspicious site.

Troubleshooting an SSL error 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 their decryption by hackers (i.e. gaining access to your data) is much higher. This leads to a not very favorable situation:

First, SSL errors can very easily occur where there is actually no danger; second, on the contrary, really experienced hackers can force the protocol to trust certificates where danger is present.

The main security measures and troubleshooting 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 them on tablets without much need on suspicious sites.
