I am trying to switch two .it (Italian) domain names to Cloudflare. They are registered with Godaddy. Whenever I try to switch the name servers to the ones specified by Cloudflare, Godaddy returns an error. I have spoken to Godaddy support who tell me this is because the name servers are not authoritative, which is required for .it domains.
Other posts here suggest this could be because the domains I’m trying to switch were previously added to another account. It claimed that this should eventually resolve itself, however two months later I’m still getting the same error when I try to switch name servers. Is there any way to resolve this?
