How to Fix \u201cERR_QUIC_PROTOCOL_ERROR\u201d in Google Chrome<\/h2>\n
There are a handful of troubleshooting solutions you can apply. By the time you are done with one or a few of them, the error will have been taken care of.<\/p>\n
- \n
- Disable the QUIC protocol.<\/li>\n
- Remove or disable third-party browser extensions.<\/li>\n
- Disable your firewall temporarily.<\/li>\n
- Disable the VPN\/proxy when logging into your user account.<\/li>\n
- Reset Chrome to its default settings.<\/li>\n<\/ol>\n\r\n\tBefore we begin, try to load the web pages using another browser, such as Edge, Firefox, Opera, or Safari.<\/p>\n
If they don\u2019t go through and the error message is displayed, then it means that the fault doesn\u2019t lie with Chrome. Check your internet connection and try again.<\/div>\r\n<\/div>\n

\nBut if the pages load successfully on another browser, you can go ahead with the solutions below.<\/p>\n
Fix 1: Disable the QUIC protocol<\/h3>\n
This is the easiest way to resolve the issue. It may suffice, and you won\u2019t have to try any other fix.<\/p>\n
Follow these simple steps to get it done:<\/p>\n
- \n
- Launch your Chrome browser.<\/li>\n
- Go to the URL bar and type (or copy and paste) \u201cchrome:\/\/flags\u201d<\/em> (don\u2019t include the quotes), and then press Enter.<\/li>\n<\/ul>\n\r\n\r\n
![\"Type]()
chrome:\/\/flags<\/em>\" class=\"lazyload screenshots__image\">\r\n <\/div>\r\n <\/div>\r\n<\/div>\n- \n
- On the page that opens, you\u2019ll find a list of experimental features. Under the Available<\/em> section, scroll down and locate Experimental QUIC protocol<\/em> (to make things easier, you can type the name in the Search flags<\/em> box at the top of the page).<\/li>\n
- Expand the drop-down menu beside the option and select Disabled<\/em>. Immediately you do so, a dialog will appear at the bottom of the screen, prompting you to relaunch your browser so as to apply the change. Click the button to restart your browser.<\/li>\n
- After Chrome restarts, the experimental QUIC protocol will now be disabled. See if the error has been successfully resolved.<\/li>\n<\/ul>\n
If it happens that the problem somehow persists, go ahead and apply the next fix.<\/p>\n
Fix 2: Remove or disable third-party browser extensions<\/h3>\n
Although third-party extensions enhance the functionality of your browser and offer a customized web surfing experience, they can sometimes cause unexpected issues like \u201cERR_QUIC_PROTOCOL_ERROR.\u201d This is especially true with unknown extensions or those designed to block ads, page pop-ups, and so on.<\/p>\n
Therefore, you should disable your extensions and see if there\u2019s one that\u2019s causing the error.<\/p>\n
Follow these easy steps:<\/p>\n
- \n
- Launch Google Chrome.<\/li>\n
- Type (or copy and paste) \u201cchrome:\/\/extensions\u201d<\/em> in the address bar and press Enter.<\/li>\n<\/ul>\n\r\n\r\n
![\"Type]()
chrome:\/\/extensions<\/em>\" class=\"lazyload screenshots__image\">\r\n <\/div>\r\n <\/div>\r\n<\/div>\n- \n
- On the page that opens, click the toggles on the available extensions to disable them.<\/li>\n
- Restart the browser and see if the error will still occur when you try to load a website. If it doesn\u2019t, then go back to chrome:\/\/extensions<\/em> and enable the extensions you trust. This way, you can figure out the one that caused the issue and remove it.<\/li>\n<\/ul>\n

\nFix 3: Disable your firewall temporarily<\/h3>\n
Windows Firewall monitors and controls incoming and outgoing network traffic. It protects your private network against malicious software<\/a> and keeps unauthorized users from accessing files on your computer.<\/p>\n
If you have another security program that serves the same function, you can try disabling Windows Firewall temporarily. See if that helps in resolving the \u201cERR_QUIC_PROTOCOL_ERROR\u201d issue.<\/p>\n
\r\n\tPRO TIP<\/div>\r\nWe recommend trying out Auslogics Anti-Malware.<\/a> The tool is fully compatible with Windows, so you won\u2019t be running into any compatibility issues on your PC.<\/p>\nWith that, Auslogics Anti-Malware will detect even the rarest malicious items learning on your PC and help you easily schedule automatic scans for ultimate protection.<\/div>\r\n

- \n
- Press the
Windows logo key + R<\/code> combination on your keyboard to bring up the Run dialog.<\/li>\n- Type \u201cControl Panel\u201d<\/em>\u00a0in the text field and press Enter or click OK.<\/em><\/li>\n
- In the window that opens, select Category<\/em> in the View by:<\/em>\u00a0drop-down in the top-right corner of the screen.<\/li>\n<\/ul>\n
\r\n\r\n![\"Select]()
Category<\/em> in the View by:<\/em> drop-down\" class=\"lazyload screenshots__image\">\r\n <\/div>\r\n <\/div>\r\n<\/div>\n- \n
- Click on System and Security > Windows Firewall.<\/em><\/li>\n
- On the left-hand side of the screen, click on Turn Windows Firewall on or off.<\/em><\/li>\n
- Select Turn off Windows Firewall (not recommended)<\/em>\u00a0and click the OK<\/em> button to save the change.<\/li>\n<\/ul>\n
\r\n\r\n![\"Select]()
Turn off Windows Firewall (not recommended)<\/em>\" class=\"lazyload screenshots__image\">\r\n <\/div>\r\n <\/div>\r\n<\/div>\nNow, try to visit the website once more. If the problem still occurs, go back and enable Windows Firewall again.<\/p>\n
You can also disable the firewall on your antivirus program. See if that makes any difference. If it doesn\u2019t, then you should enable it again.<\/p>\n
We also suggest you follow the steps below to check if there\u2019s a problem with your firewall or proxy settings<\/a>. The error in discussion occurs when Google fails to receive data from your end.<\/p>\n
Here is how to check your LAN settings:<\/p>\n
- \n
- Go to Control Panel, as already shown above.<\/li>\n
- Select Large icons<\/em> in the View by:<\/em>\u00a0drop-down.<\/li>\n
- Click on Internet Options<\/em>.<\/li>\n<\/ul>\n
\r\n\r\n![\"Click]()
Internet Options<\/em>\" class=\"lazyload screenshots__image\">\r\n <\/div>\r\n <\/div>\r\n<\/div>\n- \n
- In the window that opens, go to the Connections<\/em> tab and click the LAN Settings<\/em> button. Review the settings and make sure there is no problem.<\/li>\n<\/ul>\n
Fix 4: Disable the VPN\/proxy when logging into your user account<\/h3>\n
Some ISPs (Internet service providers) differentiate user accounts. They display a login prompt for you to enter a username and password<\/a> before you can access the Internet.<\/p>\n
To fix the QUIC protocol error issue, try disabling your VPN or proxy while logging into your user account.<\/p>\n
Here\u2019s how:<\/strong><\/p>\n
- \n
- Go to the Start menu.<\/li>\n
- Click on Settings.<\/em><\/li>\n
- Click Network and Internet > Proxy.<\/em><\/li>\n
- Click the toggle to turn on Automatically detect settings.<\/em><\/li>\n<\/ul>\n
\r\n\r\n![\"Toggle]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\n- \n
- Click the toggle to turn off the Use a proxy server<\/em>\u00a0option.<\/li>\n<\/ul>\n\r\n\r\n
![\"deselect]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\n- \n
- Go back to Network and Internet<\/em> and click on VPN<\/em>.<\/li>\n
- Select the connection you want to remove and click the Remove<\/em>\u00a0button.<\/li>\n
- Click Remove<\/em> to confirm.<\/li>\n<\/ul>\n
In the event that you just subscribed to the ISP and don\u2019t have the username and password, confirm from them whether they have such a security protocol in place.<\/p>\n
Fix 5: Reset Chrome to its default settings<\/h3>\n
Resetting Chrome might fix the issue. But keep in mind that your search engine settings, home page, and pinned tabs will be cleared. Also, all browser extensions will be disabled, and temporary files (including cookies and cache) will be erased.<\/p>\n
However, saved passwords, bookmarks, and history will not be affected.<\/p>\n
Here\u2019s how to reset Google Chrome:<\/strong><\/p>\n
- \n
- Launch the browser.<\/li>\n
- Click the Menu<\/em> icon (three vertical dots) in the top-right corner of the screen and select Help > About Google Chrome<\/em>.<\/li>\n
- In the window that appears, select Reset settings<\/em>.<\/li>\n
- Click on Restore settings to their original defaults.<\/em><\/li>\n
- Now, click the Reset settings<\/em> button to confirm the action.<\/li>\n
- Restart Chrome and see if the error occurs.<\/li>\n<\/ul>\n
