[AG-TECH] Bridge Problem

I have been having a problem using any bridge from AG3.  From the log file, it seems that the xml-rpc call is failing with a 404 error.  I have had a snoop around, and found that it is trying to connect to the bridge on port 1992 and make and XMLRPC call.  I have tried this call myself from a terminal, and the call works fine i.e. no 404 error.  I am not sure therefore what is going wrong in the Venue Client with this.

I have pasted the log extract file after my signature.
