Fastpath Web not showing Workgroups

I am having issues with the setup of the Fatpath Web Plugin. I believe the reason is thatI setup the xmpp domain with this name so my users ids would be the same as their emails. but the actual name of the server is server.domain.com.

xmpp.domain

domain.com

I would like to my server like this as it its already in production. How can I configure the Fastpath web so it will communicate with the Fastpath server?
