Error while writing to an Azure Worker role Input Endpoint - azure

Question

I'm trying to create an azure application which can recieve messages on a TCP port. I have configured an input endpoint shown below :
Endpoint Name:GPRSEndpoint
Type:Input
Protocol:TCP
Port:10000
My azure worker role code looks like this:-
TcpListener listener = new TcpListener(RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["GPRSEndpoint"].IPEndpoint);
listener.ExclusiveAddressUse = false;
listener.Start();
while (true)
{
Thread.Sleep(100);
if (listener.Pending())
{
Trace.WriteLine("Incoming Request", "Information");
TcpClient c = listener.AcceptTcpClient(); //waiting for client to connect
Stream s = c.GetStream();
StreamReader sr = new StreamReader(s);
string text = sr.ReadLine();
if (text != null && text.Length > 0)
{
Trace.WriteLine("Saving GPRS Packets into Storage Table", "Information");
//Saving GPRS Packets into Storage Table
Site site = new Site();
site.GPRSPacket = text;
var insertOperation = TableOperation.Insert(site);
siteTable.Execute(insertOperation);
}
c.Close();
}
Trace.TraceInformation("Working", "Information");
}
}
And finally my client program looks like this:-
TcpClient c = new TcpClient();
Console.WriteLine("\nConnecting to Azure...");
IPAddress AzureWorkeraddress = IPAddress.Parse("168.63.239.54");
//String AzureWorkeraddress = "http://clienttcpcloud.cloudapp.net/";
//IPAddress AzureWorkeraddress = IPAddress.Parse("65.52.184.129");
c.Connect(AzureWorkeraddress, 10000); //Azure Worker Role's INPUT TCP Endpoint 168.63.239.54 or (http://clienttcpcloud.cloudapp.net/)
Console.WriteLine("\n<<<<<<<<<<<<<<<<<<Server Connected>>>>>>>>>>>>>>>>>>\n");
Console.WriteLine("Sending to Azure...");
Stream s = c.GetStream();
StreamWriter sw = new StreamWriter(s);
sw.WriteLine(text);
sw.Flush();
Console.WriteLine("\n\nGPRS Packet Sent!!!");
s.Close();
c.Close();
I've tried changing the port number to several values, but it still fails to respond. The error that i get is:-
**A Connection failed because the connecting party did not properly respond after a period of time, or the established connection failed, because connected host failed to respond 168.63.239.54:10000**
I really don't know what the problem is.....

There is a sample application at http://blog.maartenballiauw.be/post/2010/01/17/Creating-an-external-facing-Azure-Worker-Role-endpoint.aspx. Have you tried that and compared what it is doing to what you are doing?
