When you apply for a white label on Peerwallet and are approved, you are assigned a custom IP address, here is how to use the IP address;
Log in to your domain provider, and create a custom name server using your preferred name using the IP generated.
You could do something like
Using your custom IP address
When that has been created, then add the names as your nameservers for your domain.
If you are using a subdomain, you would need to modify the A records to point to the IP address given.
Add the domain to the configuration page for your custom domain at
Sellers -> Configuration -> Custom domain
You should set this before enabling this; the system would check if it points, if not, you would receive an error.
If you have done this properly and you still get an error, then you should wait for some hours to try again probably the DNS should propagate and it should be ready when you want to try.
