Hi there!

I recommend you to check:

• Origin CA certificates · Cloudflare SSL/TLS docs → make sure that you have this:

List the hostnames (including wildcards) the certificate should protect with SSL encryption. The zone apex and first level wildcard hostname are included by default.

• Gathering information for troubleshooting sites · Cloudflare Support docs → Reviewing Certificates with cURL, including the test with that specific hostnames, and use the OpenSSL or SSL Checker to understand what’s the specific error.

Take care!

@AlphaK Actually, It doesn’t worked with
Full (strict) mode
Encrypts end-to-end, but requires a trusted CA or Cloudflare Origin CA certificate on the server
