How to Fix ‘ERR_SSL_PROTOCOL_ERROR’ on Google Chrome?

A short guide on how to repair the ‘This site cannot provide a safe link’ or ‘ERR SSL PROTOCOL ERROR’ for Chrome.

If Google Chrome is your gateway into the internet world, you must have experienced an error in “This site can not provide a safe link” or at least once in an ERR SSL PROTOCOL ERROR message. The frustrating thing about this error (really, the family of errors) is that a lot of time behind it there’s no easily discernible cause. The SSL errors will show up on both the most common and the least popular pages. Heck, I’ve got one on here, on our website, and I can assure you that our SSL / TLS setup is up to snuff.

As we have just mentioned, as far as the explanation why Google often says “This site can not provide a stable link” is concerned, it is almost impossible to pin it down to one source. From a problem as insignificant as an incorrect device date to far more perplexing server problems it can be anything – it could be almost anything.

For a moment let ‘s put the diagnostic aspect aside and concentrate on what you’re here for – the treatment.

A fast troubleshooting guide for repairing ERR SSL PROTOCOL ERROR on Google Chrome is here. If one is not working, then try the next. You should be able to get rid of this problem, sooner or later.

Fix ERR_SSL_PROTOCOL_ERROR by setting the correct Date & Time

Sounds too easy, aren’t they? Well, the best solution to a problem is the right one, most of the time. In this case, defective date & time settings can cause you trouble. But make sure your machine doesn’t lag behind, or sprint ahead.

Why is that an issue? Certificate validity is an incredibly important element in the authentication process , ensuring that very precise tabs are held when the certificate was signed and when it expires. If there is a problem with the time and date of your device, it can trigger problems of all kinds during authentication. These browsers are built to err on the cautionary side, which is why anything as simple as getting the wrong time can cause an error in SSL link.

Fix ERR SSL PROTOCOL ERROR by clearing Browsing Data in Chrome

From one solution to another which is apparent.

If you’ve already got the right date & time, it’s time to clear cache and cookies for Chrome. To do so, click Ctrl + Shift + Remove and delete data from your browsing. Even if the “This site can’t provide a safe link” error hasn’t been resolved, we suggest you clear your browsing data periodically.

Fix ERR_SSL_PROTOCOL_ERROR by clearing your SSL State

If none of these works, the next thing you can do is to clear your SSL State. To do so follow the steps below:

  1. First, go to Google Chrome customize and power, the three dots you see just below the X (close) icon.
  2. Now press Settings.
  3. Scroll the page down, and open the Advanced Settings.
  4. By scrolling down or searching in the search bar, go to Open proxy settings.
  5. A window will open, called ‘Internet Resources.’
  6. Go to the Content window and press the State Clear SSL button.
  7. Address ERR SSL PROTOCOL ERROR with QUIC Protocol deactivation
  8. Fast UDP Internet Connections (QUIC) offers an equivalent TLS / SSL link to Google’s servers. In Chrome the QUIC protocol is supported by default.
  9. Copy chrome:/flags/#enable-quic to disable it, and paste it into the address bar, click enter.
  10. The Experimental QUIC Protocol would be set as Normal on top of your computer.
  11. Disable it and get Chrome relaunched.

We don’t usually prescribe this, but in some odd situations, it has been known to function so we put it on the list.

Fix ERR_SSL_PROTOCOL_ERROR by checking your Antivirus Settings

Warning: This move is not completely safe as it makes the older, vulnerable SSL / TLS protocols still being used by some of the websites.

You may not know this, but your Antivirus program keeps an eye on the web pages you are visiting and protects you from any risks that they may pose or involve. It does this by testing whether a website uses the SSL / TLS protocol. It prevents you from accessing the site after finding the protocol unsafe and out-of-date.

There is no single way for all Antivirus apps to adjust the settings as the UI and settings vary from one device to another. You will like to find out to see if it tests the SSL protocols. If it does, turn it off and see what happens. Revert to the original settings if the problem continues.

Fix ERR SSL PROTOCOL ERROR by triggering the last resort of all SSL / TLS versions
Warning: This move is not completely safe as it makes the older, vulnerable SSL / TLS protocols still being used by some of the websites.

When you visit an SSL-enabled website, it will communicate with the server using SSL / TLS protocols. Often a website’s SSL / TLS version may not be compatible with your Chrome version, since Chrome does not enable obsolete SSL / TLS protocols to run by default. You ‘d need to change those settings for the SSL / TLS protocol. Here’s how to do it:

  1. Tap the three dots you see in Chrome’s top-right corner, and press Settings.
  2. Now scroll down to Advanced Settings.
  3. Search and open the Proxy Settings.
  4. Click Changed
  5. Scroll down before Security arrives. Now make sure all of the SSL and TLS versions have been tested.
  6. Select File.
  7. Restart Chrome.
