StartServer listen failed on NetworkLobbyManager

So I was working on a custom NetworkLobbyManager script when I got the error "StartServer listen failed.". The following code snippet is what I'm using on a GUI button:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using UnityEngine.UI;
4. using UnityEngine.Networking;
5.  
6. public class MainLobby : NetworkLobbyManager {
7.  
8.  
9.     public void HostGame()
10.     {
11.         SetPort();
12.         NetworkLobbyManager.singleton.StartHost();
13.     }

I made it the first function so you could see all of the import settings etc. I have no clue what's wrong though. My custom NetworkManager follows a similar design structure and works without any hiccups. Any thoughts?

EDIT: I got it working. The server wouldn't spawn a player object, so I just did an override function. For some reason I cannot get the scenes to change though. Servers can change manually with a NetworkLobbyManager.ServerSceneChange(), but clients will not change with it

 

Have you managed to get it working ?

 

I have not. I won't be able to work on it for another five or six hours, as I have afternoon and night courses in college today.

 

Note that the server will only change map when all the players are ready.
