When calling WCF duplex service hosted on Azure throwing error as "An existing connection was forcibly closed by the remote host"

Hi,

I am working on windows 8 app which is using wcf duplex messaging for two way communication between server and client.

I have deployed my duplex WCF service on Azure portal which is using TCP binding. I have tested this service on local IIS and everything is working fine. Only on Azure it is giving me errors.

The error details are as follows

Message: The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:00:59.7149641'.

Inner Exception:  "An existing connection was forcibly closed by the remote host"

SocketErrorCode: System.Net.Sockets.SocketError.ConnectionReset

StackTrace:    at System.ServiceModel.Channels.SocketConnection.HandleReceiveAsyncCompleted()
   at System.ServiceModel.Channels.SocketConnection.OnReceiveAsync(Object sender, SocketAsyncEventArgs eventArgs)

I have created a singleton class which creates a client proxy and then call the wcf method like this

var result= await ProxySlate.GetInstance().GetClientProxy.GetUserInfoAsync();
