I am experiencing the same exact issue. I was with chat support and they said it was working on their end. Before I was disconnected I tried a few of their suggestions, "try in private browsing" which did not make any difference. I am in line again for another chat.
My domains are managed by GoDaddy. The domain I setup to forward was previously configured to point another host. Now shutting down that site/hosting and moving to one of my GoDaddy WordPress hosted sites.
