Nat Target 0 not connected to Nat Facilitator

Unity Engine

Hi everyone,

i’m currently building a game in 2d… that i previously started in 3d.

My 3D game work fine and my network is working as intended!

but now that i started my 2 game in a new project
i got this error each time i try to connect to my server…

what can cause the probleme…
i have the same port of my 3d game and they dont run at the same time… why does the 3d game work and my 2d game got a error of nat.???

2

the worse part is … the GUI from unity 4.6 make it fail…

cause i tried with the GUI.Button fashion and it work perfect… my player can connect to the server

Working Code

using UnityEngine;

namespace Assets.Scripts.Network
{
    public class NetworkManager : MonoBehaviour
    {
        public Transform[] SpawnPoints;
        public GameObject PlayerPrefab;

            {
                if (GUI.Button(new Rect(50, 50, BtnW, BtnH), "Start Server"))
                {
                    StartServer();
                }

                if (GUI.Button(new Rect(50, 100, BtnW, BtnH), "Refresh"))
                {
                    Debug.Log("Refreshing...");
                    RefreshHostList();
                }

                GUILayout.BeginArea(new Rect(Screen.width - 500, 0, 500, Screen.height), "Server List");
                GUILayout.Space(20);

                foreach (HostData hostedGame in MasterServer.PollHostList())
                {
                    GUILayout.BeginHorizontal("Box");
                    GUILayout.Label(hostedGame.gameName);

                    if (GUILayout.Button("Connect"))
                    {
                        UnityEngine.Network.Connect(hostedGame);
                    }

                    GUILayout.EndHorizontal();
                }

                GUILayout.EndArea();
            }
        }

    }
}

my start server button = StartServer
my connect button = RefreshHostList
my Room button = ConnectToRoomEvent(roomName)
