What errors do you see while adding it?

Error Adding Domain…

This could be due to already adding the domain to this or another account or, you have not changed the nameservers as required or not enough time has passed since changing the nameservers.

Remember, you need to change the nameservers on a domain via registrar control panel BEFORE adding it to your account, it may take 24~72 hours to completely update the nameservers.:

Please verify your nameservers and/or change them to :

(The nameservers are changed via your domain registrar control panel, NOT your hosting control panel.)

After changing the nameservers you may have to wait 24~72 hours prior to being able to add the domain to your account. .

Once the name servers are set it may take upto 76 hours before the domain can be added here.

Name servers MUST be set before adding the domain here, if your registrar REQUIRES that you add a domain before setting the name servers then you will need to use a different domain name / registrar (or contact there support requesting they manually set the name servers). We are NOT able to add domains to the vPanel without the name servers being set firstly. If this is a requirement, please UPGRADE, on our premium hosting we do allow domain names to be added without the name servers being set. Please do NOT create a support ticket unless you have waited at least 48 hours after succesfully changing name servers / adding domain. Please do NOT create a support ticket unless you have waited at least 48 hours.

As the error message says, you need to change your domain's nameservers through your domain registrar control panel. That's the panel of the company where you bought your domain name (which is as far as I can tell, but you know that better than I do).

Right now, your domain name is still using the nameservers of ``, but has NS records referring to our nameservers. That won't work, and won't properly direct your domain name to us.

So please login to the panel of your domain registrar, change the nameservers and then wait a few hours before trying again.
