afther a few shots the cube die`s but the RPC is not Working Sending The damage Ifo to all the Players

also i am just beginning to understand C#

this is on my cube

using UnityEngine;
using System.Collections;

public class EnemyHealth : MonoBehaviour
{
    public int maxHealth = 100;
    public int curHealth = 100;

    void Start()
    {
        //dh = GameObject.Find("HealthBar").GetComponent<DisplayHealth>();
    }

    void OnGUI()
    {
        // GUI.Box(new Rect(10, 40, healthBarLength, 20), curHealth + "/" + maxHealth);
    }
    
    void OnCollisionEnter(Collision collision)
    {
        if (collision.gameObject.tag == "Bullet")
        {
            AddjustCurrentHealth(-10);
            //dh.ShowHealth(curHealth);
        }
    }
    [PunRPC]
    public void AddjustCurrentHealth(int adj)
    {
        curHealth += adj;

        if (curHealth < 0)
            curHealth = 0;

        if (curHealth > maxHealth)
            curHealth = maxHealth;

        if (maxHealth < 1)
            maxHealth = 1;

        if (curHealth < 10)
            Destroy(gameObject);

       // healthBarLength = (Screen.width / 2) * (curHealth / (float)maxHealth);
    }
}

this is on my rocket

using UnityEngine;
 using System.Collections;
[PunRPC]
public class Rocket : MonoBehaviour
{
    public float damage = 10.0f;

    // Use this for initialization
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {

        if (Input.GetButtonDown("Fire1"))
        {
            RaycastHit hit;
            Physics.Raycast(this.transform.position, transform.position, out hit);

            // we hit something...
            if (hit.collider != null)
            {
                hit.collider.GetComponent<PhotonView> ().RPC ("AddjustCurrentHealth", PhotonTargets.All, damage);
                //hit.transform.GetComponent<Health>().Damage(10.0f);
            }
        }
    }
}

does the box have a “network view” component attached?
