I have solved.
It seems the error was here:

NetworkComms.AppendGlobalIncomingPacketHandler<string>("aliveTest",
			                                                       (packetHeader, connection, incomingString) =>
			                                                       {
try {

Toast.MakeText(this, incomingString,ToastLength.Short).Show();
Console.WriteLine("... Incoming message from " +
				                  connection.ToString() + " saying '" +
				                  incomingString + "'.");

}catch (Exception err){
Console.WriteLine(err.Message);
}	
});

incomingString.ToString(); <—— Original code copy and pasted from your sample 🙁
