Mapping not working in Plesk

Trying to map the domain from
http://www.darwin.mba to coachinglife.pro

No dedicated IP configured at the moment, so trying to make this work via changing the nameserver.

www has been set as a CNAME for darwin.mba. We currently use Amazon's Route53 for DNS, so they actually set different name servers with each new DNS that's configured.
