Not Connecting to Server

So, i'm making a game in Unity. It's multiplayer. For my specific 'needs' I had to create my own Network Manager. That's what I did. Everything appears to work fine, and it does, except for one thing: It's not connected to the server. Even though i've set up hosting, server running, and connecting, it supposedly is never actually connected. Please help. Here's the code for my Network Manager class: using UnityEngine; using System.Collections; using UnityEngine.Networking; using UnityEngine.SceneManagement;

enum PlayMenuMode { Home, Connect, Server, Connected, None }

public class PlayMenu : NetworkManager {

 PlayMenuMode menu = PlayMenuMode.Home;
 NetworkClient client;
 int port = 4855;
 string ip = "127.0.0.1";
 short playerConnection;

 void OnGUI()
 {
     if(menu == PlayMenuMode.Home)
     {
         if(GUILayout.Button("Singleplayer/LAN"))
         {
             menu = PlayMenuMode.None;
             Host();
         }
         if(GUILayout.Button("Connect"))
         {
             menu = PlayMenuMode.Connect;
         }
         if(GUILayout.Button("Start Server"))
         {
             menu = PlayMenuMode.Server;
         }
     }

     if(menu == PlayMenuMode.Connect)
     {
         GUILayout.Label("IP To Connect");
         ip = GUILayout.TextArea(ip);
         GUILayout.Label("Port To Use");
         port = int.Parse(GUILayout.TextArea(port.ToString()));
         if(GUILayout.Button("Connect")){
             Connect();
             menu = PlayMenuMode.Connected;
         }
         if(GUILayout.Button("Back"))
             menu = PlayMenuMode.Home;
     }

     if(menu == PlayMenuMode.Server)
     {
         GUILayout.Label("Port:");
         port = int.Parse(GUILayout.TextArea(port.ToString()));
         if(GUILayout.Button("Start Server")){
             NetworkServer.Listen(port);
             menu = PlayMenuMode.None;
         }

         if(GUILayout.Button("Back"))
             menu = PlayMenuMode.Home;
     }

     if(menu == PlayMenuMode.Connected)
     {
         Transform regionManager = GameObject.Find("_REGIONS").transform;
         for(int i = 0; i < regionManager.childCount; i++)
         {
             if(GUILayout.Button(regionManager.GetChild(i).name))
             {
                 menu = PlayMenuMode.None;
                 SceneManager.LoadSceneAsync(regionManager.GetChild(i).GetComponent<RegionController>().objectSourceScene, LoadSceneMode.Additive);
                 GameObject playerGO = (GameObject)Instantiate(Resources.Load("Player"), Vector3.zero, Quaternion.identity);
                 NetworkServer.AddPlayerForConnection(client.connection, playerGO, playerConnection);
                 playerGO.transform.tag = "Local Player";
                 Camera.main.gameObject.SetActive(false);
                 playerGO.transform.FindChild("Camera").gameObject.SetActive(true);
             }
         }
     }

 }

 void Host()
 {
     NetworkServer.Listen(4855);
     client = ClientScene.ConnectLocalServer();
     client.RegisterHandler(MsgType.Connect, OnConnected);
 }

 void Connect()
 {
     client = new NetworkClient();
     client.RegisterHandler(MsgType.Connect, OnConnected);
     client.Connect(ip, port);
 }

 public void OnConnected(NetworkMessage msg)
 {
     Debug.Log("Connected To Server");
     menu = PlayMenuMode.Connected;
 }

 public override void OnServerAddPlayer(NetworkConnection conn, short playerControllerID)
 {
     playerConnection = playerControllerID;
 }

}

I also get these errors: Local invoke: Failed to find local connection to invoke handler on [connectionId=0] for MsgId:12 Local invoke: Failed to find local connection to invoke handler on [connectionId=0] for MsgId:4

And I get these, but i'm pretty sure it's not from the net code: GetLocalizedString can only be called from the main thread. Constructors and field initializers will be executed from the loading thread when loading a scene. Don't use this function in the constructor or field initializers, instead move initialization code to the Awake or Start function.
