If you’re getting the ERR_SSL_PROTOCOL_ERROR or SSL Connection Error on Google Chrome, you’re not alone. Almost every user has encountered this kind of error at least once. The ERR_SSL_PROTOCOL_ERROR isn’t a big deal and can be solved by applying some pretty straightforward steps. So, what are you waiting for? Let’s evict this annoying error from our lives.


Why are you getting ERR_SSL_PROTOCOL_ERROR?

Well, we can’t connect our system to yours and can’t find out the reason behind it. What we can do is we can give you some reasons that could be causing this problem. It could even be multiple reasons teaming up to leave you in a lurch.

These problems range from inaccurate date & time to a firewall blocking your browser extension…it literally could be anything. Most of the times this error occurs as a result of server problems. But you’re not here for diagnosis, are you? Here is the list of medicines you should try one after the other until one works.

So, take one pill at a time and see what happens. Maybe call us in the morning if problem persists.

1.      Set correct system date, time & region

Ever came across a philosophical principle called “Ockham’s Razor”? If not, go ahead and Google it. And of course, don’t forget to check system date & time.

Date and Time Settings

2.      Clear Chrome’s cache and cookies

Clear them ASAP by pressing Ctrl + Shift + Delete. Keep doing this on regular basis to avoid any infections!

3.      Disable QUIC Protocol

If you’re facing this error frequently, this might just be the pill you’ve been looking for. To disable QUIC protocol, follow these steps:

  • Open Google Chrome, copy and paste chrome://flags/#enable-quic and press enter.
  • If the Experimental QUIC Protocol is set as Default or Enabled, change it to Disabled.
  • Now go to the bottom of the page and click on Relaunch Now.

Extension Disabled

If this doesn’t work, take the next pill.

4.      Disable extensions

Extensions are great and we all love them. But sometimes the things that we love do us the most damage. Keep an eye on our blog for more on this, but right now we must focus on ERR_SSL_PROTOCOL_ERROR and its extensions.

Keep disabling each and every extension one by one until you find the real culprit.

5.      Remove your system’s hosts file

Here’s how you can remove your system’s hosts file:

  • Open Run by pressing Windows logo key and R
  • Type C:\Windows\System32\drivers\etc in the Open: search space and press
  • Right-click on the hosts file and press Delete.

Delete Hosts File

Restart and check if this worked or not.

6.      Clear SSL State

If your SSL is getting in the way, you need to clear it. Do it by following the steps below:

  • First, go to Start Menu > Control Panel > Network and Internet > Network and Sharing Center.
  • Now click on Internet Options on the bottom left corner of the page.
  • You’d be seeing the Internet Properties Go to the Content tab and click on Clear SSL State.

SSL Certificate

Now your SSL State should have been cleared. Restart Chrome and see if it the ERR_SSL_PROTOCOL_ERROR still persists.

7.      Lower your internet security and privacy level

If you’ve set your security level too high, it might be stopping you from visiting a particular site. Follow these steps to lower them [Note: Do this at your own risk].

Security Level

  • First, go to Start Menu > Control Panel > Network and Internet > Network and Sharing Center.
  • Now click on Internet Options on the bottom left corner of the page.
  • You’d be seeing the Internet Properties Go to the Security tab and set the security level to Medium. Do the same with the Privacy tab located just beside the Security tab.

8.      Disable your security tools for a moment

If you have enabled Windows Firewall or Antivirus or both, disable them for a moment and see if it has any effect.

We hope any of these steps helped you get rid of ERR_SSL_PROTOCOL_ERROR.
