[UNET]Disconnecting from network doesn't destroy the player.

Hi, I am remastering the question made in 2012 to the actual system,

My player prefab is not being destroyed nor on disconnection and neither on client crash, I tryied to override the OnServerDisconnect function and test from a list where I save all players into classes if they are online.

I am using 2 systems to check if players are online and destroy them, both are not working. (I have a host based game, so everything is managed from clients and on the player network behavior I am using a lot of if(isServer) to manage the game.

System 1 In NetworkManager_custom

 public override void OnServerDisconnect(NetworkConnection conn)
     {
         Destroy(conn.playerControllers[0].gameObject);
         NetworkServer.Destroy(conn.playerControllers[0].gameObject);
     }

I am sure all connection can just have 1 controller

System2 In MyManager

 public void Update()
     {
         if(isServer)
         {
             for (int i = 0; i <  PlayersList.Count; i++)
             {
                 if(!PlayersList[i].PlayerGameObject.GetComponent<NetworkIdentity>().connectionToServer.isConnected 
                 && !PlayersList[i].PlayerGameObject.GetComponent<ClientCommands>().ReturnLocal())
                 {
                     Destroy(gameController.players[i].PidgeonGameObject);
                     NetworkServer.Destroy(gameController.players[i].PidgeonGameObject);
                 }
             }
         }
     }

Thanks in advice
