ESDM in E10 Blank Title 135087

We have upgraded to 10 but cannot get ESDM to work. I am getting the following

System.ServiceModel.ProtocolException: You have tried to create a channel to a service that does not support .Net Framing. It is possible that you are encountering an HTTP endpomt. ---> System.IQ.InvahdDataException: Expected record type 'PreambleAck', found '72'. 

Any suggstions as to what we are doing wrong?
