WCF related - System.ServiceModel.FaultException: The message could not be processed - vb.net

Question

This is similar to: http://social.msdn.microsoft.com/Forums/vstudio/en-US/71c31684-1ce7-4fd9-bf24-674e6dc707bf/the-message-could-not-be-processed?forum=wcf
However, I did not forget an entry like that person did yet I still get the same error.
I get:
System.ServiceModel.FaultException: The message could not be processed. This is most likely because the action 'http://tempuri.org/IBackupServerService/DeleteBySpaceIdProcess' is incorrect or because the message contains an invalid or expired security context token or because there is a mismatch between bindings. The security context token would be invalid if the service aborted the channel due to inactivity. To prevent the service from aborting idle sessions prematurely increase the Receive timeout on the service endpoint's binding.
Note: I'm hosting the service from a console app on a server and then calling the service from a web app located on another server.
My client web.config file looks like: (Note: the "IP address" and "userPrincipalName" are both fictitious for this posting.)

Any ideas?
