.NET On-Premises/Cloud Hybrid Application Using Service Bus Relay not working

Hello,

I'm trying to create a POC to use the Azure Service Bus relay to share data between an Azure application and a web service hosted elsewhere. I am referring to this link and followed the exact steps as mentioned the web tutorial.

I have Trial version of Azure account and Using VS 2013 installed with Azure .NET SDK for VS 2013.

I could able to run the WCF service and deploy the web application to Azure. When I run my web application I'm ended up with TimeoutException as shown below:

[TimeoutException] : The request has timed out after 00:00:00 milliseconds. The successful completion of the request cannot be determined. Additional queries should be made to determine whether or not the operation has succeeded.

I tried setting "OperationTimeout" by casting my channel to IContextChannel as shown below, but still the exception persist.

if (channelFactory.State == CommunicationState.Opened)
{
      IContextChannel contextChannel = channel as IContextChannel;
      contextChannel.OperationTimeout = new TimeSpan(0, 10, 0);
}

Tried setting openTimeout, closeTimeout, sendTimeOut and recieveTimeout in both client and server config as shown below :

<bindings><netTcpBinding><binding name="netTcpRelayBinding" openTimeout="00:10:00"
         closeTimeout="00:20:00" receiveTimeout="00:10:00" sendTimeout="00:10:00"></binding></netTcpBinding></bindings>

Though I'm getting TimeOutException.

I'm not sure about the root cause of the problem and not getting any solution online.

Please suggest me on this.

Thanks in advance.
