I am to trying to use Plesk WHM. I recently added a domain on WHM application and from DNS settings I copied the DNS and try to point into domain management. I am using domain.com as a registrar. when I try to add new DNS. it gave me error "Invalid nameservers supplied. Please verify your nameservers are correct." is there any I am missing

I talked to domain.com support and they said it's the issue with the name server. please guide me in the right direction if I am missing any step.
