Hello there CF community!
From yesterday I have a strange error.
I have a website that has a Lets Encrypt certificate which is valid.
If I do not proxy through cloudflare I can visit the SSL version of it correctly.
When I proxy it through CF, I get an ERR_SSL_VERSION_OR_CIPHER_MISMATCH error. If I unproxy it, it works correctly.
- The site has been proxied through CF for like 2 years now without any problem.
- On the Edge Certificates, the Universal certificate stays at “Pending Validation (TXT)”. I tried disabling/enabling Universal SSL with not any success.
For now I have unproxied the website from CF but I would like to know why this error keeps comming up.
I have other websites in the same server with same SSL options on both server and CF side and there is no error.
