DH Jabber no longer talks to Gtalk?

All of my Gtalk “buddies” disappeared from my Jabber roster about a month ago. Maybe at about the same time DH started offering Google Apps. The XML console in PSI tells me that the connection to talk.google.com fails

Server Connect Failed

Anyone else getting this? Is there a work-around, or do I have to register an @gmail.com account and use a separate connection instead of federated jabber?
