Question 2: How can you troubleshoot the 'err_ssl_protocol_error' on GitHub Pages?

First, verify that your GitHub Pages site is properly configured to use HTTPS. Check the 'SSL' settings in your GitHub Pages dashboard to ensure the correct certificate is selected and that it's valid. Inspect the server logs for more detailed error messages that might pinpoint the exact cause of the problem. Also, ensure your server's firewall isn't blocking HTTPS traffic.
