The most popular web browser of all time is Google Chrome. Like some other internet users, you probably like its quick, slick interface and experience. Some computer flaws are more precisely targeted than others, and some are so specialized that they only affect a few Internet browsers. Refreshing the page usually makes the “ERR SSL PROTOCOL ERROR” warning disappear.

As the name suggests, an SSL protocol error occurs when a web browser cannot establish a secure connection. Of course, this happens on an SSL certificate-enabled website. 

Google Chrome shows the “Your connection is not private” warning when it finds something fishy regarding a website’s SSL/TLS certificate. But the root causes of some errors are still unknown, and the ERR_SSL_PROTOCOL_ERROR message is one of them.

The server, which is outside your control, browsers, or a modification to your PC settings could all be responsible for these issues. You might be unable to access your favourite websites if Chrome’s ERR SSL PROTOCOL ERROR occurs.

We’ve highlighted several ways to rapidly and correctly fix the ERR SSL PROTOCOL ERROR issue in Google Chrome. One of these will fix the problem, allowing you to access your preferred website as quickly as possible. If you find yourself in this situation, please read on.

What Is ERR_SSL_PROTOCOL_ERROR in Google Chrome?

Google Chrome displays the error message ERR SSL Protocol Error on websites. Most people are aware of the error message that shows when we try to open certain websites. Most of the time, this error is caused by server difficulties and a lack of client authentication.

When a user tries to access an SSL-protected website through Google Chrome, and the secure connection fails, the error message ERR SSL PROTOCOL ERROR, often known as “this site can’t provide a secure connection,” appears.

Various faults with your website server or local computer, or a combination of both, can produce this error. It’s most prevalent on Chrome, but it varies depending on your browser.

What Does “ERR SSL PROTOCOL ERROR” Mean in Chrome?

The ERR SSL PROTOCOL ERROR notification indicates that your browser is no longer compatible with the ERR SSL PROTOCOL ERROR protocol. It is unable to access the website you are attempting to view. Since the ERR SSL PROTOCOL ERROR protocol is pre-installed in Chrome, it is the only browser to experience the “ERR SSL PROTOCOL ERROR” problem.

This typically occurs when you use a Google-owned website like Gmail or YouTube. Deprecated networking protocol ERR SSL PROTOCOL ERROR has an open specification. Chrome has a protocol called ERR SSL PROTOCOL ERROR that enables website loading while also supporting internet security. It might also help with several typical HTTP problems.

Unlike ERR SSL PROTOCOL ERROR, which allows several files to be downloaded simultaneously, HTTP, for instance, can only download one file at a time. This error may indicate a problem with your internet connection, IP settings, or network security. Occasionally, all it takes is to use an outdated browser.

This problem might inevitably affect other websites in addition to the one you’re attempting to access right now. Depending on the underlying problem, there are several ways to resolve the ERR SSL PROTOCOL ERROR in Chrome.

How to Fix the ERR_SSL_PROTOCOL_ERROR in Chrome

Now let’s get down with our main event and learn how to fix the problems. Use the simple steps below.

Step 1: Disable Browser Extensions

This might be the source of the issue if you have many browser extensions activated. Disable each browser extension one at a time to determine if any are causing HTTPS queries to fail.

To disable Chrome extensions, go to More Tools > Extensions from the popup menu by clicking the three dots symbol in the upper right corner of the browser window.

Toggle all of the enabled browser extensions off one by one to disable them, returning to your site in between. Remove or deactivate any extensions that appear to be causing the ERR SSL PROTOCOL ERROR problem until you can learn more about the cause of the fault.

If there isn’t a resolution for the problem shortly, it’s probably preferable to uninstall the extension entirely.

Step 2: Sync the System Date

The most common reason for this error is the incorrect date on your system. Your system’s date should always be synched with the date of the website’s server.

When the system date is not synced with the server date, you might expect the ERR_SSL_Protocol_Error to occur. This situation can easily be fixed by adjusting the date of your system. You can adjust it manually or auto-sync the date and time with the internet. After fixing the date and time issue, reload the website, and you will see this error disappear.

Step 3: Update your browser

This stage may be difficult for some people, but don’t worry because we have illustrated the processes. Just adhere to the steps.

Check to see if Chrome has already received an update, though. To verify it,

Begin by clicking the three vertical dots in the top right corner of your browser. Go to Help > About Google Chrome after that.

By selecting this option, you can see and learn more about the version you are now using. Your browser will then update itself if necessary. Use the browser only once this upgrade has been made. Restart your browser as instructed in step one, then try to view the website you’ve chosen.

Continue to the following step if the issue doesn’t go away. 

Step 4: Renew the IP and clean up the DNS

If you’ve tried the steps above and you’re still getting the ERR SSL PROTOCOL ERROR warning, your Domain Name System may be the cause (DNS).


  • Press the Windows key and type CMD while on the desktop.
    Run as administrator by choosing the right-click Command Prompt.
  • In the command prompt, type ipconfig /release and hit the Enter/Return key on your computer to submit the command.
  • Wait a little while for a response stating that the IP address has been disclosed.
  • In the command prompt, type ipconfig /renew and hit the Enter/Return key on your computer to submit the command.
  • Wait a short while for confirmation that the IP address has been restored.
  • In the command prompt, enter or press return after typing ipconfig /flushdns.
  • Close the command window and try connecting again.

Step 5: Delete Your Browser’s Cache

This is very crucial. We frequently neglect to erase our internet history. A browser will always store your history if you need to find your way back to a maybe forgotten internet site you once visited. Even though it’s your personal computer, the truth is that it might be used against you by partners, friends, coworkers, teachers, and even law enforcers.

Follow the instructions below;

  1. Launch Chrome on your computer.
  2. Toggle to “More” at the upper right.
  3. To clear browsing data, select “More tools”.
  4. Pick a time at the top.

Select “All time” to delete everything.

Ensure the boxes next to “Cookies and other site data” and “Cached pictures and files” are checked.

Tap Clear data.

Step 6:Clear the SSL State in Chrome

The SSL state saves the cache memory of SSL certificates placed on previous sites you’ve visited. Even if the website has fixed the problem, the browser may display the ERR SSL PROTOCOL ERROR notice if it previously utilized an unsecured SSL certificate. You may not only get rid of SSL-related cache memory but also improve the efficiency of your browser by erasing the SSL state.

  • Navigate to the menu (three vertical dots on the right side of the screen).
  • Go to the Settings tab.
  • Select Advanced from the drop-down menu. On the right-hand side of the screen, there’s a navigation bar.
  • Locate the System option in the menu and select Open your computer’s proxy settings.
  • There will be a new window open. Lookup Internet Options.
  • To clear the SSL state, go to Content and select Clear SSL State.

How do I fix a secure connection that failed in Chrome?

If you have antivirus software that offers “HTTPS protection” or “HTTPS scanning,” you’ll encounter this error. Chrome is unable to provide security because of the antivirus. Turn off your antivirus program to resolve the issue. When using secure sites, switch off this program if the website functions after turning it off.

Why does Google Chrome say not secure?

Because the web page or website you are viewing does not provide a secure connection, you get the “Not Secure” warning. When you connect to a website with Chrome, you have the option of using HTTP (insecure) or HTTPS (secure) (secure). The “Not Secure” notice will appear on any page that uses an HTTP connection.
