When you use your computer, you may encounter a situation where you cannot open a web page and display an error code like ERR_SSL_PROTOCOL_ERROR. Usually, this happens when the browser is using a protocol to establish a secure connection to the site. Nevertheless, there are several ways you can solve this tricky problem.
When your computer's system time is wrong, it may cause ERR_SSL_PROTOCOL_ERROR, so you can adjust the system time by following the steps below.
You can press Win + I to open the settings and select Time & language on the left pane. And click Date & time on the right pane.
In the new window that appears, click the toggle button next to Set time automatically and Set time zone automatically to turn them on.
Cleaning up your computer's SSL state can also help you resolve SSL-related issues, and you can follow the navigation below to do so.
Click on Windows Start and type Internet Options. Open the matched item.
