ERR_SSL_PROTOCOL_ERROR SSL Protocol Error – What To Do? Here Are 8 Fast Fixes


Once, when I turned on my computer, I tried to access a favorite and regularly visited the website, and suddenly received an unpleasant “gift” from the browser in the form of a message: “Error 107 (net:: ERR_SSL_PROTOCOL_ERROR): SSL protocol error.“.

It’s no secret that very often when you log in to a certain resource or when you authorize a site, the user receives a message that an SSL error (SSL_ERR_PROTOCOL_ERROR) has occurred, and the requested page does not open. Why? This is what we will now find out, and at the same time, we will consider possible causes of its occurrence and the simplest methods of elimination.

Trying to find out the causes of dysfunction, I began to visit other familiar sites, trying to track which of them had a similar message. Some sites did not want to load, giving an error ERR_SSL_PROTOCOL_ERROR, while I visited others without any problems, and no SSL protocol error occurred.

Trying to understand the reasons for the problem of downloading sites, I had to study many sources, and now I will tell you what needs to be done to remedy this situation with the ERR_SSL_PROTOCOL_ERROR SSL protocol error if you also encountered it. So, first things first.

What is this ERR_SSL_PROTOCOL_ERROR error?


As you know, SSL is a cryptographic protocol that ensures the security of Internet connections and, until recently, was widely used for instant messaging: in an e-mail, Internet faxes, IP-telephony, and others. It has several vulnerabilities, and today, SSL is increasingly being replaced with more reliable TLS.

However, at this time, all major browsers still use the SSL protocol, so any user may encounter problems using it, in particular, with the mentioned error 107 (as well as similar 101 and 112), which occurs when a connection is compromised.

This error ERR_SSL_PROTOCOL_ERROR SSL is especially common on Google Chrome, but it is also common on other browsers. To solve this problem, you need to take a series of actions, which I will discuss below.


For starters, it would not hurt to check your computer for viruses using special programs such as Trojan Remover or Dr.Web CureIt. The reason for the incorrect operation of your browser may be precisely in infecting your computer with various malicious programs.

Checking the system for viruses

The error code ERR_SSL_PROTOCOL_ERROR 107 does not indicate a specific reason. Nevertheless, it is believed that one of the possible, besides the most common options could be damage to the HOSTS file due to exposure to viruses or malicious codes.


What to do in such a situation, I think, is already clear. It is advisable to check the system is not a regular scanner, but some portable, independent utility.

Unfortunately, some viruses can also “hang” in RAM, so for correctness, it is worth using boot disks like Kaspersky Rescue Disc, which load their interface even before Windows starts and carry out a full comprehensive scan.

# Method 1: Check the date and time?

You may be surprised, but this factor may be the cause of error 107. Check the correct date and time in the computer settings, and if necessary, change the date and time to the correct ones by right-clicking on the time bar at the bottom right of the screen.

  1. Select “Set date and time”;
  2. And then click on “Change date and time,” enter the correct data and confirm the changes.

# Method 2: Change the settings of the antivirus

Go to your antivirus settings and try to disable the HTTPS protocol check temporarily. This is especially true for owners of the Eset Smart Security Nod32 5 antivirus, many of them have solved the problem in this way.

  1. If you have Eset, then go to the settings, there choose “Internet and e-mail”;
  2. Next “Internet Access Protection,” select “HTTP, HTTPS” and tick the box “Do not check the HTTPS protocol”;
  3. Click “OK” and confirm the action.

In addition, such antiviruses as Avast or Kaspersky can intercept SSL connections and use their certificate when surfing the Internet, often far from perfect. Try disabling the check of SSL connections in the specified antivirus programs.

In addition, you can try to put your browser on antivirus exceptions, at least temporarily. This can help resolve an SSL protocol error called ERR_SSL_PROTOCOL_ERROR.

# Method 3: Disable anti-virus check


Quite often, there is a problem that antivirus packages block SSL-connections. In most cases, this is characteristic of the Eset Smart Security package, starting with the fifth version.

To fix the problem, it is recommended to disable HTTPS and SSL checking in the antivirus, as well as to use the exclusion list to add browser application to it In other antivirus programs, and this situation can also manifest itself. In general, the output is the same.

# Method 4: Use the exception list of the firewall

The list of exceptions is useful when changing the settings of the firewall. This mainly concerns the error ERR_SSL_PROTOCOL_ERROR Google services, the search engine itself, or even a browser.

As is already clear, you need to go to the security settings and add the appropriate Internet application to the list of allowed nodes. It is also advisable to clean the cookies and the cache in the Google Chrome browser if you use it by deafult.

You can also try setting automatic proxy settings in the browser, but this is not always necessary. In theory, the problem should disappear.

# Method 5: Choose a different browser

Now a few words about preferences in terms of used Internet browsers. Not all of them are equivalent, and the problem is when all of a sudden the error SSL error “ERR_SSL_PROTOCOL_ERROR” appears, for this reason, may be associated with such software. True, the situation here is more with outdated software, so it is advisable to upgrade the default browser version to the latest.

However, according to some experts, ideally, it is best to use standard Internet Explorer, although many people don’t like it. In the tenth version of Windows, there is no such problem. There, the Edge browser, which replaced the standard Explorer, is more powerful.

Nevertheless, the standard Windows browser with the settings and default parameters does not create such a problem (unless it is only when the user changes it).

# Method 6: Update the operating system


Sometimes the problem of the appearance of failures during the SSL connection may be that the latest updates are not present on the system.

However, for the most part, this applies to Windows XP with the obligatory installation of Service Pack 3. Installing the appropriate update in many cases solves the problem.

# Method 7: Check the browser or firewall?

Try lowering the level of protection to the firewall and refresh your browser. If you are using it for a long time, an old browser version may cause error 107.

# Method 8: Try CCleaner


According to some users, cleaning the system using the CCleaner program helps to deal with this error in the browser effectively. Try to take advantage of the possibilities of CCleaner and you.
