ServerRPC not reacting to call

I have recently been trying to learn and make a multiplayer game. but during so i encountered a problem. the problem being that my client cant call my ServerRPC. and i have no idea why, i have tried everything i can think of.

Code (CSharp):

1. using Unity.Netcode;
2. using UnityEngine;
3.  
4. namespace Game
5. {
6.     public class Player : NetworkBehaviour
7.     {
8.         public float Speed;
9.  
10.         public NetworkVariable<Vector3> Position = new NetworkVariable<Vector3>();
11.  
12.         public override void OnNetworkSpawn()
13.         {
14.             if (IsOwner)
15.             {
16.                 Move();
17.             }
18.         }
19.  
20.         [ServerRpc]
21.         public void SubmitPositionRequestServerRpc(ServerRpcParams rpcParams = default)
22.         {
23.             Position.Value = this.transform.position;
24.         }
25.  
26.         public void Move()
27.         {
28.             if (NetworkManager.Singleton.IsServer)
29.             {
30.                 Position.Value = Position.Value = this.transform.position;
31.             }
32.             else
33.             {
34.                 SubmitPositionRequestServerRpc();
35.             }
36.         }
37.     }
38. }
