How can I fix 'err_ssl_protocol_error' by checking the date and time on my iPad?

Incorrect date and time settings can interfere with SSL certificate validation. To fix this, go to Settings > General > Date & Time. Ensure 'Set Automatically' is toggled on. If it's already on, toggle it off, wait a few seconds, and then toggle it back on. If automatic setting doesn't work, manually set the correct date and time.
