Method 4: Disable the QUIC Protocol 

If clearing your SSL state did not help, then you can disable the QUIC Protocol. Most of you might not know how to do it and thus seem a daunting task, but it is easy! 

Follow the steps given below to Disable the QUIC protocol:

  • Open Google Chrome
  • In the address bar, paste the following URL and search:
  • Below the Experimental QUIC Protocol highlighted in yellow, press the Default button
  • A list of options will open; click on Disabled to disable the QUIC protocol

Now, reopen Chrome to check if it worked or not! 

Method 5: Temporarily Disable the Antivirus

It might sound bizarre, but often your Antivirus causes the err_ssl_protocol_error. Most Antivirus software that uses advanced technologies scans every website visited to check if it contains any malware or anything that would threaten your security or not.

As a part of it, Antivirus assesses the SSL version of sites you open. Suppose the website that you open is using an older SSL version, then Antivirus would not allow the website to open and instead block the site.

However, you can resolve the issue by disabling the Antivirus program. You need not think it over much as after you finish browsing then; you can enable it once again. Disabling the Antivirus temporarily will fix the issue if your Antivirus caused it. 


Method 6: Check Firewalls 

If you use the Intranet or Extranet, you will have Firewalls active. Suppose you open a website that exists in a blocklist of Firewalls; then, it will stop Chrome from loading the website for you. In such a scenario, check the blocklist on Firewalls, remove the website if it is present and reload it. 

Method 7: Disable the Extensions and Add-ons

Chrome allows the use of Extensions and Add-ons that enables you to extend the functionalities of browsers. However, these Extensions and Browsers become trouble for you as they cause unnecessary errors like the err_ssl_protocol_error.

However, to fix the issue, you can Disable Chrome Extensions one at a time and reload the site to check whether it works. After disabling an Extension, if the issue is fixed, then keep that one Extension disabled and enable others. Use a similar approach for Add-ons also. 

But if it also doesn’t work. Internet Settings on your system are causing the issue. Here’s how you can fix it! 


Method 8: Change your Internet Security and Privacy Levels

If your system has high Internet Security and Privacy levels, then it blocks several sites from loading on your system resulting in the err_ssl_protocol_error. 

You can modify the Internet Privacy and Security levels by following the steps given below: 

  • Open the Control Panel of your PC
  • In the search box, input Internet Options and press the Enter key
  • Internet Properties dialog box would open 
  • Go to Security Tab
  • The slider would be set too high, so set it to the medium by sliding it towards the middle and pressing the OK button

Launch Chrome and open the website which was generating the err_ssl_protocol_error. The issue would now be fixed!
