Problem with SSL Version /Missmatch for a specific subdomain

Getting the following error ERR_SSL_VERSION_OR_CIPHER_MISMATCH when trying to access a site on our QA server but works just fine.

SSL Is enabled and flexible, using both HTTP and DNS proxying on the dns page. Out of ideas what the problem is at the moment.

➜  ~ openssl s_client -connect

Hosts on the fourth level are not supported by Cloudflare’s universal certificates. You’d need a $10/month dedicated one in this case.
