Error 525 SSL Handshaking Failed

Hello There
I was activating SSL on one of the domain i have added into my account, I have added other domains as well and all of the domain are hosted on same server, and SSL is working perfectly for the rest of them except one, on which i am getting this error 525 ‘handshaking failed’. What could be the possible reason for this and please help me out with the solution.
Thanks and regards

Possibly the certificate on your server is invalid or SSL is not activated. Did you check it?
Another reason could be that your server doesn’t accept connections in port 443

The most common causes include:

  • The origin web server does not have a valid SSL certificate installed.
  • The origin web server is not listening on port 443 (or other custom secure port).
  • The origin web server does not support or is not configured properly for SNI.
  • The cipher suites that Cloudflare accepts and the cipher suites that the origin server supports do not match.
