Everything You Need to Know About err_ssl_protocol_error on Google Chrome

If you’re encountering the err_ssl_protocol_error on Google Chrome, there are a few ways you can try to fix it.

First, check if the issue is specific to Chrome by trying to access the same website on a different browser like Mozilla Firefox. If the error occurs on multiple browsers, it could be a problem with the website itself.

Next, clear your browser’s cache and cookies. Sometimes, outdated or corrupted website data can cause connection issues. To do this, go to the Chrome settings, navigate to the “Privacy and security” section, and click on “Clear browsing data.”

If clearing the cache doesn’t work, try disabling any extensions or plugins that might be interfering with the SSL connection. You can do this by going to the Chrome settings, selecting “Extensions,” and turning off any extensions that might be causing the problem.

If none of these solutions work, it’s possible that the website you’re trying to access has an SSL error. In this case, there isn’t much you can do on your end, as the issue is on the website’s side. Contact the website administrator or try accessing the website at a later time.

Correct the Date and Time on your system

1. Click on the Date and Time display on your taskbar.
2. Select “Adjust date/time” from the drop-down menu.

4. If the toggle switch is already on, try turning it off and then on again to refresh the connection.
5. Additionally, make sure the time zone is correctly set for your location.
6. After making any changes, close the settings window and restart your computer.

Correcting the Date and Time on your system can help resolve ERR_SSL_PROTOCOL_ERROR and other connection issues in Google Chrome.
