Quick Guide to Fixing ‘ ERR-SSL-PROTOCOL-ERROR ‘ Chrome

Google

Almost everybody who is on Google Chrome must have received at least one error message from the’ ERR SSL PROTOCOL ERROR’ or “This site can’t connect securely.”

Okay, why does this error message appear? The truth is that there is no discernible reason; it appears at any given time on any website. In reality, there could be many factors. It may be due to database issues or sometimes even to machine information or time inaccuracy.

So, if you face such a mistake, what’s the remedy? How can I repair it? Here are a couple of tips to fix the’ ERR SSL PROTOCOL ERROR’…

Try to Correct the Date and Time of the Process

As we said before,’ ERR SSL PROTOCOL ERROR’ could be due to a device date or time error. Only test whether there is any inaccuracy. If an inaccuracy occurs, the reliability of the certificate and the authentication method may cause problems. So just correct the process date and time if there is a mistake; that could solve the problem itself.

Try clearing the browsing data for Google Chrome. Open Google Chrome, Ctrl + Shift + Delete and simple browsing data as well as cache & cookies. In fact, your browsing data should be clear periodically.

Try to clear your state of SSL

The next thing you can do is clear your SSL nation. You can do this by following these steps.

  •  Click on the three points under Close (X), which reads’ Customize and monitor Googles Chrome.’
  • Choose settings.
  • Down scroll and click on’ Advanced’
  •  Click on “Open Proxy Settings”
  • Click on the’ Data ‘ tab in the’ Web Assets ‘ window, then press Clear SSL State.’

Seek to Deactivate the QUIC Protocol

Google Chrome enables by default the QUIC (Quick UDP Internet Connections) protocol that offers an equivalent TLS / SSL connection to Google servers. You must try to deactivate it. (Well, although this is not a recommended choice, in some cases it works). This can be achieved by:

  •  Open Chrome
  • Enter’ chrome:/flags’ on the address bar and hit enter.
  • Go to the’ Default’ table on the top of the window next to the Experimental QUIC protocol.
  • Adjust it to’ Disabled’ from’ Default.’
  • Chrome restart.

Try to Check your Antivirus Software

An antivirus software can track all the visited web pages, shielding the user from all kinds of threats. This is done by checking the SSL / TLS protocol on the website. The Website is blocked if the SSL / TLS protocol is outdated and unsafe. Check the settings of your antivirus software, see if you are scanning SSL / TLS protocols. Once SSL / TLS protocols are scanned, disable them and see if the error persists. If so, return to the original setup.

We would not like to test and change antivirus settings as it could end up with an antivirus that could allow an insecure SSL / TLS page configuration, causing security problems.

Try to Allow all Versions of SSL / TLS

If a website version of SSL / TLS can not be compatible with the Google Chrome version you are using, instances could occur. In this case, you can try to change the protocol settings for SSL / TLS. In reality, it’s pretty dangerous and therefore safer to avoid.

You can do this by following these steps.

  •  Click on three points below the Close (X) button that reads:’ Customize and monitor Google Chrome.’
  • Select modes.
  • Scroll down and click on’ Advanced’
  • Click on’ Open Settings ‘
  • Click the’ Advanced’ tab in the’ Web Properties ‘ window to open it.
  • Check all SSL and TLS versions and press’ Submit’ into the’ Privacy’ tab.
  • Chrome restart.

It’s best to avoid this, as already described. Support for obsolete SSL and TLS versions with known vulnerabilities can endanger you.
