Error 1016; both domains on CF


I have two domains on CF, let say A & B.

  • Domain A is using CF Workers to serve everything; there’s no server involved, no CNAME or A record. Its working fine on its own.

  • Domain B has a CNAME pointing to domain A.

I get Error 1016 whenever I try to access domain B.

Am I missing something?

Is Domain B set to :orange: in DNS? A 1016 often implies you’re trying to put Cloudflare in front of a server that’s already on Cloudflare.
