There still something not clear. The error message you have reported: "Discard UDP packet from..." appears only for incoming packets. If the server is the only one sending data and the client is not firing any updates I can't see how this can cause such an error. Am I missing something el...

So let me understand the communication better. The server sends "move data" to clients every 40 millisec. But how often each client is updating their position in your test? In test they are not updating positions. They only recive data and do nothing with it. In original project clients i...
