I have a free account and use a wildcard rule (DNS only) on a domain. Today some subdomains stopped working because of a certificate issue. I noticed that the wildcard DNS entry was wrongfully pointing to CF IP’s instead of my own. For one domain i got:
curl: (35) error:14004410:SSL routines:CONNECT_CR_SRVR_HELLO:sslv3 alert handshake failure
for the other one i got a redirect to the URL i requested (infinite loop). here is an example request-id:
< CF-Cache-Status: DYNAMIC
< cf-request-id: 04fb9a09820000ede748b97200000001
< Server: cloudflare
< CF-RAY: 5cd92c559c15ede7-CDG
after changing the IP address in the wildcard rule and instantly changing it back everything startet working correctly again.
