There are a few possible reasons for a domain registration error message:
Domain name already exists
If the domain status says "already exists", then someone else had already registered the domain name. In this case, your request will be cancelled and you will not be billed for the domain.
Domain setup error
If you change the DNS of your domain before the registration process is complete, an error will occur. Please reset the DNS back to 1&1 Name Servers, wait for the domain to be completely registered and then modify the DNS.
Error during registration
The status "errors" means that an error occurred when a registration request was filed. Please contact our technical support staff at email@example.com
. This may delay the registration of your domain for approximately 48 hours.
