Basically, this error means that there is a problem with the use of the Chrome browser , including the “QUIC” function for high-speed Internet connections. This “QUIC” protocol was designed and developed by Google to improve the performance of connection-oriented web applications.

It is important to note that most of the sites that are normally searched on the Internet do not have this protocol, but the sites that are connected to Google do. This applies, for example, to the YouTube platform and other web-based products that Google offers to users around the world through your browser.

What is the ERR_QUIC_PROTOCOL_ERROR?

Le message ERR_QUIC_PROTOCOL_ERROR_PROTOCOL_ERROR
The ERR_QUIC_PROTOCOL_ERROR message

As the name suggests, this error indicates a problem with Chrome’s use of its Quick UDP Internet Connections feature ( QUIC protocol ).

The QUIC protocol was developed by Google and improves the performance of connection-oriented web applications.

According to W3Techs , only about 3.2% of websites on the Internet use the QUIC protocol, which means most of the websites you use will not use this protocol.

However, since Google developed the protocol for its own products, most of Google’s sites use QUIC ( including YouTube ). So while the overall protocol usage rate is not high, the fact that Google uses QUIC means that you will be interacting with sites using QUIC almost every day.

Sometimes the ERR_QUIC_PROTOCOL_ERROR_PROTOCOL_ERROR message can be directly caused by the protocol, but it can also be caused by a problem with your internet connection (or VPN / proxy) or a problem with a browser extension.

Also, this error has nothing to do with your WordPress site. However, this can sometimes prevent you from accessing your WordPress site , which is why I’m helping you solve this problem.

Also note that the ERR_QUIC_PROTOCOL_ERROR message may appear in the Chrome browser due to Internet connection problems. In particular, it could be a bug with a VPN / proxy server or an extension added to Chrome. Here we explain the solutions for this error, with simple steps and care, you can fix it in time.

Error messages like err_quic_protocolo_error

If you see an error, you will likely see a detailed message about the problem as well. The message sounds like one of the following examples:

  • This page is currently inaccessible.
  • The page may be temporarily down or may have been permanently moved to a new web address.
  • Error code: ERR_QUIC_PROTOCOL_ERROR.
  • NET: ERR_QUIC_PROTOCOLO_ERROR.
  • ERR_QUIC_PROTOCOLO_ERROR YOUTUBE

These errors prevent users from browsing certain Internet pages. Google is always striving to test the latest innovations to improve the web connection and the overall user experience.

QUIC, short for Quick UDP Internet Connections, is a protocol that allows Google to increase speed to avoid secure Internet connections. Therefore, many of Google’s activities on the Internet use this protocol to establish a connection. Therefore, if this error occurs, the problem is most likely in your browser, specifically in Google Chrome.

How To Fix Err_Quic_Protocol_Error In Google Chrome

Although this error has become common, its true cause is unfortunately still unknown. Generally, the problem is believed to be caused by a bug in the Google Chrome configuration settings.

However, it can also be due to a software conflict or even connectivity issues. Although the cause of this problem is unknown, the process to fix the ERR_QUIC_PROTOCOL ERROR is fairly straightforward. You just have to follow the following instructions:

1. Try loading the page in another browser.

Sometimes your browser may experience problems and may encounter Err_Quic_Protocol_Error. The first step to fix this error in Google Chrome is to load the same web page in another browser , such as Edge, Firefox, or Safari.

If the page does not work as expected in other browsers, the problem is probably related to your Internet connection. If the page loads correctly in another browser, the problem is with Google Chrome and should be solved by the following method.

2. Deactivation of the QUIC protocol.

One of the most common causes of this error is related to the QUIC protocol, which helps protect against obstacles on the Internet. If the issue occurs in the middle of a website stream, an error occurs.

These are the steps to disable the experimental QUIC protocol.

  • Open the Google Chrome browser, type chrome: // flag in the address bar and hit Enter.
  • Search manually for the experimental QUIC protocol . Or press Ctrl + F on your keyboard and type QUIC in the search box at the top right. Now you can easily find the experimental QUIC protocol.
  • At the same time, you will find a drop-down menu. In the drop-down list, select the option you want to disable.
  • Now restart your browser and see if the problem is resolved.

3. Deactivation of browser extensions in Google Chrome.

Sometimes turning off QUIC experimentation doesn’t fix the problem. If you have the same problem, you should also disable third-party extensions. Disabling browser extensions solves the problem in most cases.

Here are the steps to disable browser extensions.

  • Open the Google Chrome browser, type chrome: // extensions URL in the address bar and hit Enter.
  • Check all the extensions you have , if you find any suspicious. Click the uninstall button in a particular extension’s window to remove it.
  • Restart your browser when the uninstallation is complete.

4. Restore Google Chrome.

  • Open Google Chrome and select the Chrome start menu button.
  • Select settings. Your settings appear in a new tab or window, depending on your preferences.
  • Scroll down and click Advanced.
  • Find the Reset Settings section and select it.
  • A confirmation “or reset” dialog box will appear.

5. Check your Windows Firewall or local proxy server settings.

This is the easiest method of all possible. All you have to do is:

  • Right-click the Start button and select Control Panel.
  • Then select “Network and Internet.”
  • Then press “Internet Options”.
  • A pop-up window will appear. Now click on the Connectivity option and select “LAN Settings”.
  • If there is a problem with your internet connection, fix it to get rid of ERR_QUIC_PROTOCOL.

conclusion

With the advancement of technology, our life improves day by day. Few of us thought that Google was going to change the whole world by combining it on a mobile device. Using the Internet is now as easy as learning the alphabet.

However, technical errors like ERR_QUIC_PROTOCOL ERROR can sometimes prevent smooth Internet browsing . Therefore, it is recommended to carry out a thorough analysis of the system with a professional optimization tool.

This is mainly because regular system scans are the only way to avoid such system errors, system slowdowns, or even malware infections.
