[Solved] Unet problem. The client always close when the connection is made with the host

So, this is the problem. I dont have a idea why this happen, and on the editor only this appears:

And this is the code that I'm using:

 #pragma strict
 import UnityEngine.Networking;
 import UnityEngine.UI;
 
 class NetworkManager_Custom extends NetworkManager
 {    
     function IniciarServer()
     {
         definirPorta();
         NetworkManager.singleton.StartHost();
     }
     
     function EntrarNoJogo() //ipe : String, port : int
     {
         definirIP();
         definirPorta();
         NetworkManager.singleton.StartClient();
     }
     
     function definirPorta()
     {
         NetworkManager.singleton.networkPort = 7777;
     }
     
     function definirIP()
     {
         NetworkManager.singleton.networkAddress = "localhost";
     }
 }            

I found the problem, and, at least for me, it wasnt on the connection script, but on one of the players scripts. This was the script with problem.

 #pragma strict
 import UnityEngine.Networking;
 
 var localDaArma : Transform;
 
 @SyncVar
 var armamento : Armamento;
 
 
 class Armamento
 {
     var municaoTotal     : int[];
     var municaoPente    : int[];
     var armas            : GameObject[];
     var ultimaArma        : GameObject;
 }
 
 function Awake()
 {
     //if
 }
 
 function Start () 
 {
 
 }
 
 function Update ()
 {
     if(Input.GetAxis("Arma 1"))
         MudarDeArma(1);
     if(Input.GetAxis("Arma 2"))
         MudarDeArma(2);
 
 }
 
 function MudarDeArma(arma : int)
 {
     
 }

It is a script to manage the weaponry of the player, that still to be done, but this isnt the problem. The problem was that I was trying to sync a var that was actually a constructor of a class, instead of the SyncListStruc, so, every time that the player spawn, with the script loaded, the client closes. I dont really know why this happens, but I changed that part for local management(just took off the @Syncvar attribute) and since then, the client works normally.
