Jabber ... not connecting

Hey guys. I went in and created a user for Jabber IM and I downloaded two clients, Psi and Pandion. I tried connecting with both and I have failed both times. Pandion just says disconnected and gives me the option to reconnect. Psi just sits there saying Connecting but never does. I know everything’s setup right at least I think it is. I know all the information provided is correct. For Psi, I added the account with the user name and pass and went to the Connection tab selected Manually specify Server Host/Port put in mydomain.com and 5222 but nothing happens.

Anyone have any suggestions?
