Problem with spawn player with RPC calls(c #)

Hi, im working on adventure game in multiplayer, and i made the code for spawn, but im stuck in one point, im show you the situation:

this piece of code is attached of a gameObject(DontDestroyOnLoad already placed)

 bool _isSpawned = false;
 public GameObject player;
 public List<MPPlayer> playerList = new List<MPPlayer>();

 void OnLevelWasLoaded(int level)
     {
         if (level == 1)
         {
             if (!_isSpawned)
             {
                 spawnPoint = GameObject.FindGameObjectsWithTag("spawnpoint");
 
                 networkView.RPC("Server_AssignSpawnPoint", RPCMode.All, Network.player);
 
                 _isSpawned = true;
 
             }
         }
 
 [RPC]
     public void Server_AssignSpawnPoint(NetworkPlayer playerNet)
     {
         if (Network.isServer)
         {
             for (int i = 0; i < playerList.Count; i++)
             {
                 if (playerList[i].plNetwork == playerNet)
                 {
                     networkView.RPC("Client_SpawnPlayer", playerNet, i);
                     break;
                 }
             }
         }
     }
 
     [RPC]
     public void Client_SpawnPlayer(int index)
     {
         GameObject playerNet = Network.Instantiate(player, spawnPoint[index].transform.position, spawnPoint[index].transform.rotation, 0) as GameObject; 
     }

 public class MPPlayer
 {
     public string plName = "";
     public NetworkPlayer plNetwork;
 }

This is level0 scene and when i load new level(level1) this code is called at start, in this code above there is this piece of code:

 for (int i = 0; i < playerList.Count; i++)
 {
     if (playerList[i].plNetwork == playerNet)
     {
         networkView.RPC("Client_SpawnPlayer", playerNet, i);
         break;
     }
 }

i want that the client(or server) in list call method and spawn own player character, i have specific that who must call the function is Network.player(playerNet), but when i try to spawn the console send me this message:

Can't send RPC function because the target is not connected to the server. UnityEngine.NetworkView:RPC(String, NetworkPlayer, Object[]) ConnectionScriptManager:Server_AssignSpawnPoint(NetworkPlayer) (at Assets/scripts/Network Scripts/ConnectionScriptManager.cs:270) UnityEngine.NetworkView:RPC(String, RPCMode, Object[]) ConnectionScriptManager:OnLevelWasLoaded(Int32) (at Assets/scripts/Network Scripts/ConnectionScriptManager.cs:252)

i try change playerNet with RPCMode.All and obviusly work, but for example if 2 players play, 4 character controller is spawned(2(number of players) per 2(total number of methods))

anyone can help me? :S thanks in advance :)

P.S. playerList have already list of player connected, the problem is only for call method from specific client(or server)
