What is ERR_QUIC_PROTOCOL_ERROR message in Chrome browser?

Basically this error means a problem with the use of the Chrome browser , specifically the “QUIC ” function for fast Internet connections . This “QUIC” protocol was designed and developed by Google to increase the performance of connection-oriented web applications.

It should be noted that, most of the web pages that are usually searched on the Internet do not have this protocol, but those that are related to Google do. For example, the YouTube platform and other web products that Google offers to users around the world through their browser.

It is also important to touch on this topic, that the ERR_QUIC_PROTOCOL_ERROR message in the Chrome browser may occur due to an internet connection problem . Specifically speaking, there may be a bug with the VPN / proxy server , or with an extension that is added to Chrome. Next, we explain the solutions to this error, with simple steps and with great attention you will be able to correct them in time.

Practical solutions to remove the error in Chrome browser

The methods that we will explain in this article are tested and developed by professionals in the computer network area, so you can be sure.

  • Disable the QUIC protocol in the Chrome browser.
  1. In the address bar of the Chrome browser type chrome: // flags /.
  2. Later in the window that appears, a text box will appear, type “quic” and locate the protocol that is first in the list.
  3. In the drop-down menu that says “Default” there are two options “Default” and “Deactivated”.
  4. You will select “Deactivated” and after the “Experimental QUIC” protocol is deactivated, restart the browserso that the changes are made.
  • Disable Chrome extensions.

Before we show you the steps to disable extensions, we want to remind you that it is impossible to check which Chrome extension is causing the error . So the most viable option is to disable all of them and then enable them one by one to rule out which one is causing it, let’s get to it!

  1. In Chrome’s search bar type the following chome: // extensions / and hit enter. Or you can also press the puzzle shape next to the search bar called “Extensions”.
  2. By opening a new window you will be able to see the extensions added to your browser.
  3. In each of the extensions there are two buttons that say “Details” and “Remove”, but you will press the blue buttonon the right side and it will be deactivated.
  4. After doing so, test if the error still appears by restarting the Google browser.
  • Check the Windows Proxy settings.

If you use Windows on your computer, it could be the proxy server settings that are causing the error, here we explain how to check it.

  1. Head over to the Windows image at the bottom left of your screen and tap there.
  2. Then a window with options will open. You will click on the “Settings” section that is above the shutdown option.
  3. Later you will see the configuration options, select the one that says “Network and Internet”.
  4. Now in the lower left part the option “Proxy” appears, click there to see its configuration.
  5. You will see two options “Automatic proxy activation” and “Manual proxy activation”, make sure it is disabled.
  6. Once you disable it if this is the case, check by restarting the computer for the changes to take effect. And then confirm if the error appears again in the Chrome browser.

In summary, remember the three options explained above, “Disable the QUIC protocol”, “Disable Chrome extensions” and finally “Change proxy settings”. By applying these options you can solve the error problem in Chrome once and for all in a practical and simple way.

We hope this educational and dynamic article will empower you to perform basic computer networking tasks on your Windows operating system computer.
