I am running into what seems like a very basic, 'I'm going to hate myself when I figure out the answer', sort of problem with the Mobility server.

All of my connectors look good, the users I have set up are synchronized with GroupWise just fine, but when I'm attempting to set up an android 2.2 device to access the server I keep getting the error 'Unable to open connection to server'

To cut out a possible firewall problem, I'm connected to my internal network on the phone wirelessly, I can ping the server just fine, but still can't connect.

On the server, I have the SUSE firewall turned off completely, and I can access the Synchronizer Web Admin. I have a feeling I'm missing something very simple, but I just haven't been able to locate it yet. Any ideas?
