Fix ERR_SPDY_PROTOCOL_ERROR error in Google Chrome

While browsing the web with your Google Chrome browser, if yоu frequently seе the error messagе ERR_SPDY_PROTOCOL_ERROR, here are some simple solutions that will fix your problem.

ERR_SPDY_PROTOCOL_ERROR error in Chrome

1] Update browser

As mentioned earlier, this feature was introduced a long time ago, and Google has now discontinued it. Therefore, there is almost no way you can find this protocol in the latest version of Google Chrome. In other words, if you are using an old version of Google Chrome, there is a high chance of getting this error message while browsing some websites. Therefore, you should update your browser as soon as possible. If that doesn’t help you, you may need to uninstall and reinstall the browser.

2] Flush Socket

If you have updated the browser or you are already using the latest version of Google Chrome, you can flush Socket to check whether it solves your issue or not. For that, enter the following URL in your URL bar in Google Chrome –

chrome://net-internals/#sockets

You will find a button called Flush socket pools.

Click on it to flush the socket. After doing that, restart your browser and try opening the same website.

3] Disable HTTPS Scanning

If you are using an internet security program, there is a high chance that your security shield scans the HTTPS sites for the certificate before opening them in the browser. If you are getting the issue with all the sites, you can try disabling HTTPS scanning in your antivirus. You should also check the 3rd party firewall software if you are using any.

Although these are the primary solutions to this problem, you can also try these following things –

• Flush DNS cache
• Clear browsing history, cookies, cache, etc.
• Reset Google Chrome.

Hope something helps!
