ERR_SSL_CIPHER_MISMATCH -Problem Please Help for solution

Hello everybody,
I have the following error (ERR_SSL_VERSION_OR_CIPHER_MISMATCH) on my site
( and I tried most of the suggestions provided in the community but no luck in successfully setting SSL.

please, help me troubleshoot the error.

Your ssl is set to Full (Strict) which “Encrypts end-to-end, but requires a trusted CA or Cloudflare Origin CA certificate on the server” but you have a self-signed origin cert.

Set SSL to Full v Full (strict) or get a proper cert on the origin and leave as Full (strict).

And, you can :search: for ERR_SSL_VERSION_OR_CIPHER_MISMATCH #CommunityTip for other ideas.
