Network.Connect not connecting to host data or ip address

I tried using the code below to connect to the matchmaking server and then connect over to my computer. This works perfectly on a Lan connection (Specifically on the same computer) but on different networks it does not connect at all. However, I know that the matchmaking server is working because the room name is still correctly displayed, it just does not connect to the server. I get the error message: "Unable to connect to [ip address]...". It is really weird because one: I know that my ip address is public and two: I tried connecting to the ip address with a forwarded port and that didnt work either. Im really confused....really I dont even need the matchmaking server and would prefer if I can just do portforward and it works...but no matter what I do it wont work. Can someone shine some light on this?

Thanks!

Master server code:

 private HostData[] hostList;
 private void StartServer()
 {
     Network.InitializeServer(32, 25000, !Network.HavePublicAddress());
     MasterServer.RegisterHost("NEN Server", "Room 1");
 }

 private void RefreshHostList()
 {
     MasterServer.RequestHostList("NEN Server");
 }
 
 void OnMasterServerEvent(MasterServerEvent msEvent)
 {
     if (msEvent == MasterServerEvent.HostListReceived)
         hostList = MasterServer.PollHostList();
 }
 private void JoinServer(HostData hostData)
 {
     Network.Connect(hostData);
 }
 
 void OnConnectedToServer()
 {
     Debug.Log("Server Joined");
 }

 //the buttons
 void OnGUI()
 {
     if (!Network.isClient && !Network.isServer)
     {
         RefreshHostList();

         if (GUI.Button(new Rect(100, 50, 250, 100), "Start Server"))
             StartServer();
         

         if (hostList != null)
         {
             for (int i = 0; i < hostList.Length; i++)
             {
                 if (GUI.Button(new Rect(400, 50 + (60 * i), 300, 100), hostList[i].gameName))
                     JoinServer(hostList[i]);
             }
         }
     }
 }
 void OnServerInitialized()
 {
     Debug.Log ("Ip address: " + Network.player.ipAddress);
     Debug.Log("External ip: " + Network.player.externalIP);
    
     Debug.Log ("server initialized");
 }
