Google Chrome is an all-time favourite web browser for users. Like some other internet users, you are likely pleased with the smooth, fast UI and user experience it offers. Some computer faults are more targeted than others, and some are so precise that they only impact specific Internet browsers and not others. The “ERR_SSL_PROTOCOL_ERROR” often message disappears when you refresh the page.

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.

We’ve outlined numerous solutions to repair ERR_SSL_PROTOCOL_ERROR in Google Chrome quickly and effectively. One of these will resolve the issue, and you will be able to visit your favourite website as soon as possible. If you find yourself in this scenario, read ours through the post.

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 It Mean by “ERR_SSL_PROTOCOL_ERROR in Chrome”?

When you see the ERR SSL PROTOCOL ERROR notice, your browser no longer supports the ERR SSL PROTOCOL ERROR protocol. The web page you’re trying to view is unreachable. Chrome comes with the ERR SSL PROTOCOL ERROR protocol pre-installed. As a result, Chrome is the only browser that encounters the “ERR SSL PROTOCOL ERROR” issue.

This usually happens when you utilise a Google-owned website like Gmail or YouTube. ERR SSL PROTOCOL ERROR is a deprecated networking protocol with an open specification. ERR SSL PROTOCOL ERROR is a Chrome protocol that allows a webpage to load while simultaneously providing online security. It may also aid in the resolution of several common HTTP issues.

HTTP, for example, can only download one file at a time, whereas ERR SSL PROTOCOL ERROR can download several files at the same time. This error could indicate an issue with your network security, IP setup, or internet connection. It’s sometimes as simple as using an out-of-date browser.

This issue could affect not only the site you’re trying to visit right now but also others in the future. Depending on the cause, there are numerous ways to fix 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: Updating your browser

Now, this step could be a bit tricky for some people, but don’t worry as we have put the steps picture-wise. Just follow the process. 

But first, do check your chrome if it is being updated already. To check it, 

First, click on the three vertical dots in the upper right-hand corner of your browser. Then go to Help > About Google Chrome.

This choice will display and inform you of the current version you are using. Then, if there’s a chance that your browser needs to be updated, it will do so. Don’t use the browser directly after this upgrade. Restart your browser as directed in step one and try to access your selected website.

If the problem persists, move on to the next step. [Most likely, you won’t have to]

Step 4: Clean the DNS and Renew the IP

If you’ve done everything above and still get the ERR_SSL_PROTOCOL_ERROR message, the problem might be with your Domain Name System (DNS).

  1. While on the desktop, press Windows Key and type CMD.
  2. Right-click Command Prompt and select Run as administrator.
  3. Type ipconfig /release in the command prompt and press the Enter/Return key on your keyboard.
  4. Wait a few seconds for a reply that the IP address has been released.
  5. Type ipconfig /renew in the command prompt and press the Enter/Return key on your keyboard.
  6. Wait a few seconds for a reply that the IP address has been re-established.
  7. Type ipconfig /flushdns in the command prompt and press the Enter/Return key on your keyboard.
  8. Close the command prompt and attempt to make a connection.

Step 5: Clearing Browser Cache

This is very important. Most of the time, we forget to clear our browsing history. If you need to make your way back to a possibly forgotten corner of the internet you visited once upon a time, a browser will keep your history eternally. The truth is that it may be used against you by significant others, friends, coworkers, instructors, and even law enforcement, even if it is our very own personal computer. 

Just follow the steps below;

  1.  On your computer, open Chrome.
  2. At the top right, click More More.
  3. Click More tools and then Clear browsing data.
  4. At the top, choose a time range. 

To delete everything, select All time.

  1. Next to “Cookies and other site data” and “Cached images and files,” check the boxes.
  2. Click 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.
