[FPS Multipler] Host only one that can kill.

Not sure if my post got posted. If it didn't here question. I am working on an Multiplayer fps and having some problems. I am currently using the Unity server, and having the problem of the host been the only one to kill a player. I having been looking at tutorials, and It's the first time I working with the multiplayer area. Here is my health code. I don't know if its my code or am I missing something.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.Networking;
 
 public class Health : NetworkBehaviour {
 
     [SerializeField]
     public const int maxHealth = 100;    //Heath of Iteam
 
     [SyncVar] 
     public int currentHealth = maxHealth;
 
     private NetworkStartPosition[] spawnPoints;
 
     void Start (){
         if (isLocalPlayer){
             spawnPoints = FindObjectsOfType<NetworkStartPosition>();
         }
     }
 
     public void TakeDamage (int amount){
 
         if(!isServer){
             return;
         }
 
         //Subtracts the amount(damage) from health
         currentHealth -= amount;
 
         //Checks if health is less than 0 to kill object
         if(currentHealth <= 0){
             currentHealth = maxHealth;

 
             RpcRespawn();
         }
     }
 
     [ClientRpc]
     void RpcRespawn(){
         
         if (isLocalPlayer){
             // Set the spawn point to origin as a default value
             Vector3 spawnPoint = Vector3.zero;
 
             // If there is a spawn point array and the array is not empty, pick one at random
             if (spawnPoints != null && spawnPoints.Length > 0)
             {
                 spawnPoint = spawnPoints[Random.Range(0, spawnPoints.Length)].transform.position;
             }
 
             // Set the player’s position to the chosen spawn point
             transform.position = spawnPoint;
         }
     }
 }
 

This is my Gun Script.

 using UnityEngine;
 
 public class Gun : MonoBehaviour {
 
     public float damage = 25f;    //Damage for gun
     public int damagePlayer = 10;
     public float range = 100f;    //Range for gun
     public float forceAdded;
 
     public ParticleSystem muzzleFlash; //Particle for the muzzle flash
      
     public Camera fpsCam;    //Camera
 
     // Update is called once per frame
     void Update () {
 
         if(Input.GetButtonDown("Fire1")){
             Shoot();
         }
     }
 
     void Shoot (){
         RaycastHit hit;
         if(Physics.Raycast(fpsCam.transform.position, fpsCam.transform.forward, out hit, range)){
             //Plays the Muzzle Flash
             muzzleFlash.Play();
 
             //Debug.Log(hit.transform.name);
 
             Health health = hit.transform.GetComponent<Health>();
 
             //Checks if anything was hit
             if (health != null){
                 //Calls the Target script to add damage to the oject hitted.
                 health.TakeDamage(damagePlayer);
             } 
 
             //Get whatever was hit
             Target target = hit.transform.GetComponent<Target>();
 
             //Checks if anything was hit
             if (target != null){
                 //Calls the Target script to add damage to the oject hitted.
                 target.TakeDamage(damage);
             } 
 
             //This give a force to anything the bullet hits
             if (hit.rigidbody != null){
                 hit.rigidbody.AddForce(-hit.normal * forceAdded);
             }
         }
     }
 }
