Fixing ERR_QUIC_PROTOCOL_ERROR

#1 Disable QUIC Protocol

As said by Wikipedia, QUIC is an experimental transport layer network protocol available in Google Chrome for establishing a connection between two endpoints over UDP. If something is wrong with the development side, you are more likely to get this error message while opening any website in Google Chrome. Thus, you can try disabling this experimental protocol in your browser and then check whether the issue remains or not.

  1. Open the Google Chrome and enter this in the address bar:
    • chrome://flags/
  2. After that, you need to search for Experimental QUIC protocol.
  3. Doing so will now set it to Default.
  4. You have to expand the drop-down menu and then select Disable/Turn off.
  5. Now, simply restart the browser and see if it works for you.

#2 Turn VPN/Proxy off when logging into your ISP’s account

Some of the ISPs are there, by which a particular method is used to differentiate user accounts. For security reasons, they contain a login prompt before the user can actually start using the internet.

In such case, as mentioned, a username and password are mandatory to log into your ISP provided user account.

If you have both username and password, you need to login first.

A straightforward workaround would be to turn off your VPN or Proxy while you log in to your user account.

When using an ISP for the first time and not having any username or password, asking your ISP if they have such a protocol for you or not will help you.

All the best!
