Check for any security product installed on the server or between the client
and the server.
If it works sometimes but not all the times, then maybe it is simply because
UDP is by definition an unreliable protocol. UDP packets are delivered with
"best effort". There is no guarantee that packets are delivered. In case of
congestion, many UDP packet are lost. They are also lost frequently when
sent from a high speed network to a low speed network.
