I start a thread to receive data from other Udp Clients after initiating the Udp socket.The following code is the thread for recieving data.
Once a piece of data comes,I used ‘OnDataUpdated.Broadcast(HappyString)’ to send the data to the blueprint.
This works well for about twenty minutes.However,an exception occurs after a short time.
