Mail.google.com uses an unsupported protocol

A common issue!

When you try to access mail.google.com and see an error message saying "mail.google.com uses an unsupported protocol", it's likely because your browser or device is not configured to use a secure protocol (HTTPS) to connect to the website.

Here are a few possible solutions:

  1. Check your browser settings: Make sure your browser is set to use HTTPS (SSL/TLS) to connect to websites. You can do this by checking your browser's settings or preferences. For example, in Google Chrome, go to Settings > Advanced > System > Open proxy settings > LAN settings > Use a proxy server for your LAN.
  2. Update your browser or device: Ensure your browser or device is up to date, as older versions may not support the latest security protocols.
  3. Clear browser cache and cookies: Clearing your browser cache and cookies can sometimes resolve issues like this. Try clearing your browser's cache and cookies, then try accessing mail.google.com again.
  4. Use a different browser or device: If the issue persists, try accessing mail.google.com using a different browser or device to see if the problem is specific to your current setup.
  5. Check your network settings: If you're using a public Wi-Fi network or a network with strict security settings, it's possible that the network is blocking access to mail.google.com. Try accessing the website from a different network or contact your network administrator for assistance.

If none of these solutions work, you can try contacting Google support or your internet service provider for further assistance.
