UPnP: A connection attempt failed because...
« on: June 25, 2016, 12:04:54 PM »
Duplicating the code form the example, I get this iwhen I start a server:

UPnP: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

Just calling:
  1. public int serverTcpPort = 5127;
  2.  
  3. if(TNServerInstance.Start(serverTcpPort, Random.Range (10000, 40000), lobby.remotePort, "server.dat", TNServerInstance.Type.Udp)){
  4.         twn_netName.PlayForward ();
  5. }
  6.  
'lobby' is a public field set in the Inspector with a UDP Lobby Client.

UPnP is when it tries to open a port on the router. It may or may not work depending on the router's capabilities.

What's the correct response? UDP certainly works over the router. This is converting a TNet2 game to Tnet3, and there was no such error message and it worked fine.

The expected response is "Opening TCP port 5127 on 192.168.X.X" if it's successful. You can see a similar message by launching WWServer.exe. The ports are opened for the server instance and are not related to the lobby server/client.

I don't know your router set up so I don't know what the expected response would be. I say don't worry about it.
