SSL Error (uses an unsupported protocol)



Hello Team,
I am using Let’s Encrypt Free SSL on my website ( The SSL working very fine. But when i activate Cloudflare in my siteground cpanel and enable cloudflare SSL support, It was showing error like: This site can’t provide a secure connection uses an unsupported protocol.

Please help!

Problem SSL

I believe that would happen if Cloudflare’s SSL cert for that domain hasn’t completed its setup. This would show in your Crypto tab at Cloudflare under SSL in the Status section.


If you had a working SSL before migration to CF you can continue using it but CF should have the private key. Upload your key in your panel or ask a brand new SSL from CF,
