SSL stands for Secure Socket Layer, and it encrypts data transfers between your website and users. Websites with SSL use the HTTPS prefix, while those without it use HTTP. Aside from Google Chrome, this error occurs in Microsoft Edge and Firefox.

Verify SSL Certificate Of Your Website
It is only a valid SSL certificate that can guarantee a secure connection to a web server. It’s time to double-check the site’s SSL certificate validity if you’re still getting the net::err protocol error.

You may want to disable Chrome’s ERR_SSL_OBSOLETE_VERSION Notifications if you’re using legacy TLS versions.

Due to the fact that SSL certificates have a fixed expiration date, if your current system time and date are incorrect, it may interfere with the authentication process.
For this reason, it’s critical to verify that the time and date on your local system are accurate before establishing a secure connection with the remote computer or device.
Go to settings from your Windows start menu, and then type date and time into the search box.
Enter “time” into the Find a setting text box and select “date/time” from the dropdown menu. Check the time and date are correct in the Date and time settings window before moving on to the next step.
