[SOLVED] Networking.Spawn how spawn object from server to all clients?

I’ve read all topics about networking , but still have not found a solution for this someone could help me ?
Basically what I want is to spawn different monsters in different positions and rotations in server , and all clients sync them.

Components on Object to spawn:

in case image dont show : Imgur: The magic of the Internet.

using UnityEngine;
using UnityEngine.Networking;
using System.Collections;

public class EnemySpawner: NetworkBehaviour
{
    public GameObject[] monsterType;

    GameObject[] monsterInstantiate;
    int randomizer;

    public override void OnStartServer()
    {
        monsterInstantiate = new GameObject[10];

        StartSpawner ();
    }
       
    void StartSpawner()
    {
        for(int i = 0; i < 10; i++)
        {
            Vector3 Pos = new Vector3 (Random.Range (-30, 30), 0, Random.Range (-30, 30));

            Quaternion Rot = Quaternion.Euler (new Vector3 (0, Random.Range (0f, 360F), 0));

            randomizer = Random.Range (0, 9);
            monsterInstantiate[i] = (GameObject)Instantiate (monsterType[randomizer], Pos, Rot);
            NetworkServer.Spawn (monsterInstantiate[i]);
        }
    }
}

Did you add enemy prefab into Registered Objects on NetworkManager?

Ou yes register but forget to save scene for build test , my bad and thanks!
