Try this:-

  1. Press the “Windows + R” keys together to open the run program.
  2. Now type “inetcpl.cpl” and press enter.
  3. Once the Internet Options are opened head over to the “Advanced” tab.
  4. Now scroll down till you find “TLS 1.2” and make sure that it’s unchecked.

Check to see if the issue persists.

If it does persist copy the whole description that error is giving and reply back to me with it.
