Google Chrome supports a huge variety of extensions all of which are not safe and sometimes even affect the browser’s functionality. Disabling such shady extensions might be of some help in troubleshooting this security-related error code.
3. Disable HTTP/2 on Windows Server
If HTTP/2 is enabled on Windows Server and you are using an older version of Google Chrome, there are high chances for an overflow of data between the browser and Windows Server.

4. Reset Chrome to the original settings
Misconfigured privacy and security-related settings in the Chrome browser often prevent the website from loading successfully. So, instead of changing each browser setting manually, Resetting the Chrome settings with a button click will suffice.
