Why am I receiving this error: “unable to verify existence of name server”?

If you are trying to modify your name servers and you receive the error “unable to verify existence of nameserver”, the name server you are trying to use has not yet been registered with the same domain’s Registry.

For instance, if you received “unable to verify existence of name server” while updating the name servers for EXAMPLE.COM, it means those name servers are not registered with the .COM Registry.

Even if a name server is functional, it may not be allowed by a particular Registry.  Most registries keep a list of valid name servers and any foreign name server host record must be added before it can be used.

Your Domain Provider can add the required name server to all TLD Registries for you.
