Master Server and Faciliator connection

Hello. This is my first time ever have to ask a question about Unity, as I understand most concepts of this engine. Before my question a small details of what I'm about to ask: I have Unity 4.2, I have downloaded the Master Server and Faciliator, and place them into the Dedicated Server of which I host. I am making a small Pong Game to test my Networking skills so I can be ready to make this next project I have in mind to be ready, but first I am making a small Network Test system to fully understand of how to connect and receive, and yes, its port forwarded. I have made a Hosting Server test on 1 Unity program and registered a hosting game to the Master Server with Faciliator settings to it. It works well, and seen both consoles have accepted it.

And please NOTE, that this is the tutorial I am following for the pong game:

Unity Networking: The Pong Game

Here's the script of the Server

     using UnityEngine;
     using System.Collections;
     
     public class MultiplayerManager : MonoBehaviour
     {
         // Assuming Master Server and Facilitator are on the same machine
         public string MasterServerIP = "xxx.xxx.xxx.xxx";
     
         void Awake()
         {
             Debug.Log("Starting Master Server");
             // set the IP and port of the Master Server to connect to
             MasterServer.ipAddress = MasterServerIP;
             MasterServer.port = 23466;
     
             // set the IP and port of the Facilitator to connect to
             Network.natFacilitatorIP = MasterServerIP;
             Network.natFacilitatorPort = 50005;
     
             Network.InitializeServer(4, 4848, true);
             MasterServer.RegisterHost("Game_Pong", "Goldy's Test Server", "Just testing this MasterServer out");
             Debug.Log("Master Server Started");
         }
     }
 }

Ok, now that the server is made, now for the client. So I did everything from the tutorial, but only got the Networking part to find the type of game, and get the list if available, even though it didn't say where to try to find them, like an IP address or someting. Anyways, so I followed this, and put in some Degub.Log into certain part to make sure I am getting the connection I need to get the list of games. Now, the Debug log said there is some servers up of the gameNameType i found, which is Game_Pong, but it didnt list them. I am wondering is there a full comment on how to show the list of servers than to just explain them as a short conversation? Because these types, as i am seeing them, are like quick tutorial of how to connect, instead of giving a full understanding and code idea

Here's the client to get the connection and list them.

 using UnityEngine;
 using System.Collections;
 
 public class MultiplayerManager : MonoBehaviour
 {
   // are we currently trying to download a host list?
   private bool loading = false;
 
   // the current position within the scrollview
   private Vector2 scrollPos = Vector2.zero;
 
     void Start()
     {
         // immediately request a list of hosts
         refreshHostList();
     }
 
   void OnGUI()
   {
     if( GUILayout.Button( "Refresh" ) )
     {
         refreshHostList();
     }
 
     if (loading)
     {
         GUILayout.Label("Loading...");
     }
     else
     {
         scrollPos = GUILayout.BeginScrollView(scrollPos, GUILayout.Width(200f), GUILayout.Height(200f));
         HostData[] hosts = MasterServer.PollHostList();
         Debug.Log(hosts.Length);
 
         for (int i = 0; i < hosts.Length; i++)
         {
             Debug.Log(hosts.Length);
             if (GUILayout.Button(hosts[i].gameName, GUILayout.ExpandWidth(true)))
             {
                 Network.Connect(hosts[i]);
             }
         }
         if (hosts.Length == 0)
         {
             GUILayout.Label("No servers running");
         }
 
         GUILayout.EndScrollView();
     }
   }
 
   void refreshHostList()
   {
     // let the user know we are awaiting results from the master server
     loading = true;
     MasterServer.ClearHostList();
     MasterServer.RequestHostList("Game_Pong");
   }
 
   // this is called when the Master Server reports an event to the client – for example, server registered successfully, host list received, etc
   void OnMasterServerEvent( MasterServerEvent msevent )
   {
       Debug.Log("Might have found some servers");
     if( msevent == MasterServerEvent.HostListReceived )
     {
       Debug.Log("Found some servers");
       // received the host list, no longer awaiting results
       loading = false;
     }
   }
 }
