As a test, I just changed from a server certificate to a valid  
unexpired anonymous certificate and had exactly the same result when  
trying to connect with VenueManagement3 from the same machine. I  
changed back to the server certificate and everything ran correctly  

Looks like the new venue server needs a proper server certificate.
