Register a domain name of your choosing, if you haven't already registered a domain.
I have same problem, too and I don't know how to fix it :(
Technically, it should be a hostname, not a domain, as it must resolve to an address.
Domain names (i.e. those labels which have an SOA record) don't have to resolve to addresses.
