Nameserver does not exist

I wanted to move a site to cloudflare. I already have three sites set up on my account. The nameservers on my domain do not match in name. I am not sure what to do at this point

Letting us guess is certainly not the best approach :wink:

Whats the domain?

But a mismatch in the nameserver smells like a double Cloudflare setup.

I’ve had a case where just one of my domains didn’t match the name servers as all the rest of them.

Along with letting us know the domain as @sandro said, can you aslo post a screenshot of the Name Servers part of your DNS page here?
