Photon - Cannot join same room

Question

I have a created a simple multiplayer test code. This is the intended flow of the whole game:

Connect to Master
Connect to a random Room
If no room exists, create a new one.

Problem of this is that 2 clients cannot see each other's room even if it's already created. I purposely exported a build of the game so that it will function as another client. When I run the game on Unity first, it will create a new room since no room existed yet, however when I run my exported game moments after creating the room in Unity, I still get a "no room existed" and then the exported creates a new empty room - so there are actually 2 rooms now in total.

I tried creating a specific named room yet still, the same problem happens. Here's my code:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using Photon.Pun;
 using Photon.Realtime;
 using TMPro;
 using UnityEngine.UI;
 using UnityEngine.SceneManagement;
 
 namespace KingReigns

     public class connectorHandler : MonoBehaviourPunCallbacks
     {
         public bool isConnectingToMaster;
         public bool isConnectingToRoom;
         public bool isConnectedToServer;
 
         public TMP_Text txtStatus;
 
         [SerializeField]
         private GameObject btnConnectMaster, btnConnectRoom;
 
         #region START
         private void Start()
         {
             DontDestroyOnLoad(gameObject);
 
             
 
             isConnectingToMaster = false;
             isConnectingToRoom = false;
             isConnectedToServer = false;
 
             txtStatus.text = "Not Connected";
         }
         #endregion
 
 
 
         #region UPDATE
         private void Update()
         {
 
             if(btnConnectMaster !=null && btnConnectRoom != null)
             {
                 if (!isConnectedToServer)
                 {
                     btnConnectMaster.SetActive(true);
                     btnConnectRoom.SetActive(false);
                 }
                 else

it's simple follow this steps:

step 1 check your cloud region name (e.g. eu is your cloud region name)

   if (_CloudRegiontext!=null)
     {
         _CloudRegiontext.text = $"Cloud Region : {PhotonNetwork.CloudRegion}";
     }

step 2 check your other player cloud region name , if other player cloud region is not same so goto unity editor -> window -> photon server setting (highlight setting) then under dev region inputfield enter "eu".
step 3 start game print logs about current open names, and check room list is updating or not.
Now you connect in same room
