When using Google, you may get an error that prohibits you from using the browser effectively. ERR_QUIC_PROTOCOL_ERROR is the name of this error. Certain websites become inaccessible when a message displays that says “This webpage is momentarily down” or “permanently transferred to a new web address“.
Google has implemented a function that accelerates the browsing experience. The QUIC Protocol (Quick UDP Internet Connections) was introduced in 2014. It is enabled by default, and Google Chrome uses the QUIC protocol to serve websites.
What is the meaning of ERR_QUIC_PROTOCOL_ERROR?
This problem is particularly prevalent on the most extensively used websites, such as Facebook and Gmail. The ERR_QUIC_PROTOCOL_ERROR can also be caused by third-party extensions, which can be fixed by disabling the error.
Google is a platform that most users rely on because it is one of the most reputable and widely used websites. Despite all efforts to make Google Chrome the finest, minor system problems and glitches are unavoidable. Even these websites run into problems when adding new features to improve their functionality.
The ERR_QUIC_PROTOCOL_ERROR issue inhibits users from smoothly switching. It reduces the system’s productivity.
5 Ways to Fix Chrome’s ERR_QUIC_PROTOCOL_ERROR
There are several approaches to resolving the ERR_QUIC_PROTOCOL_ERROR. We’ve taken some important steps to eliminate the ERR_QUIC_PROTOCOL_ERROR.
Method 1: Chrome:/Flags command
Step 1: To begin, open the Chrome browser and open a new tab.
Step 2: Open the Settings menu by typing “chrome:/flags” in the Address tab.
Step 3: A warning notice stating “Be careful; these experiments may bite” will appear, along with a Warning message regarding using such “experimental features“.
The method is safe, thus this message can be ignored.
Step 4: Next, check for the Experimental QUIC protocol feature by scrolling down. If you can’t find it, press Ctrl + F. A box called “Find” appears. Then, in this box, put “Experimental QUIC protocol” and press Enter.
Step 5: Finally, you’ll see a drop-down menu. Relaunch Chrome after selecting Disabled. After that, the ERR_QUIC_PROTOCOL_ERROR should be gone.
Method 2: Disabling Browser Extensions
Chrome’s functionality is greatly enhanced with extensions. They make use of the system’s resources, even while they’re not running. Some of them are underdeveloped as well. Disabling third-party extensions may assist in resolving the problem.
It can be tough to pinpoint the extensions that are causing issues. It becomes important to remove them.
To perform the procedure, follow these steps:-
Step 1: First, open the Chrome browser and create a new tab.
Step 2: In the Address bar, type “chrome:/extensions” and press Enter.
Step 3: Next, go through the Extensions and disable those that aren’t necessary.
Step 4: Finally, “Restart” the computer to examine if the ERR_QUIC_PROTOCOL_ERROR is still present.
Note: If disabling a third-party extension does not result in a change, the extension must be deleted entirely.
Method 3: Resetting the Browser
Resetting the web browser is another way to fix the ERR_QUIC_PROTOCOL_ERROR problem.
The problem can be fixed by following the instructions below:-
Step 1: Go to the Chrome browser first. Then, in the top right-hand corner, click the three vertical dots to access the “Settings” menu.
Step 2: Next, scroll down to find the “Advanced” option, which you may expand by clicking on.
Step 3: Finally, pick “Reset” and “Relaunch” Chrome from the menu.
Note: Before pressing the “Reset” button, we recommend that you save all links and tabs. It will be permanently erased throughout this process.
Method 4: Checking the Proxy or Firewall
Firewalls and proxy settings are sometimes misconfigured. It’s possible that it’ll lead to a slew of issues.
To resolve the problem, follow these steps:-
Step 1: First, go to internet properties and input the command “intelcpl.cpl” using the Windows key +R.
Alternatively, you can search for ‘Control Panel’ in the Start menu and then pick ‘Internet Options‘.
Step 2: Next, select “LAN settings” from the “Connection” menu. Make sure the Firewall or proxy browser isn’t causing any problems. If there are any errors, address them first.
Step 3: Check the “Automatically detect settings” option and uncheck the “Use a Proxy Server for your LAN” option.
Step 4: Finally, click “Ok” and “Apply” before “Restarting” your computer.
Method 5: Turn Off the Firewall for a While
The Windows firewall guards against security threats. On the other side, it also prevents access to certain websites. You must turn them off.
Follow the instructions below and put them into practice:-
Step 1: First, look in the System Tray for any anti-virus programs (depicted by an upward-facing arrow). Disable it by right-clicking on it and selecting “Disable“.
Step 2: Set a time limit for the antivirus program to be disabled, such as 15 or 30 minutes.
Step 3: Open the Chrome browser to see if the ERR_QUIC_PROTOCOL_ERROR has been resolved.
Step 4: If the problem remains, use the Search or Cortana bar to look for the “System and Security” setting. Otherwise, access the “Control Panel” by pressing the Windows key + I and selecting it.
Step 5: Next, select the “Windows Firewall” option from the left-hand panel, and then select the “Turn Windows on or off” option.
Step 6: Finally, after selecting the option to switch off the Firewall, “Restart” the machine.
Keep in mind to reactivate the Windows Firewall. Regardless of whether the ERR_QUIC_PROTOCOL_ERROR has been repaired or not, repeat the steps.
The reason for the ERR_QUIC_PROTOCOL_ERROR problem has yet to be determined. We assume that it is configured by misconfigured Google Chrome settings, program conflicts, connectivity problems, and other similar issues. IT experts, on the other hand, are still working on a solution to this problem.
Third-party add-ons, firewalls, and antivirus software can all cause issues.
When you use Incognito Mode, the ERR_QUIC_PROTOCOL_ERROR does not appear.
As a result, it displays the general location where this error is thought to originate.
Access to Google-operated websites is particularly affected.
I hope you find this information useful in resolving the ERR_QUIC_PROTOCOL_ERROR.
