For anyone else who has come across this problem here is my current workaround (until the version comes out with a fix for this issue). I call the following method prior to trying to connect with networkcomms.net. Only if this method tells me something is listening do I try and connect with networkcomms.net library.
static bool IsServerAvailable(string IPOfServer, int PortNumberToTry)
{
bool SomethingListeningOnPort = false;
try
{
System.Net.Sockets.Socket sock = new System.Net.Sockets.Socket(System.Net.Sockets.AddressFamily.InterNetwork,
System.Net.Sockets.SocketType.Stream, System.Net.Sockets.ProtocolType.Tcp);
sock.Connect(IPOfServer, PortNumberToTry);
if (sock.Connected == true) // Port is in use and connection is successful
SomethingListeningOnPort = true;
sock.Close();
}
catch (System.Net.Sockets.SocketException)
{
SomethingListeningOnPort = false;
}
return SomethingListeningOnPort;
}
