Matchmaker does not find any matches

I am trying to make a lobby for my first person shooter, and i want to have a scrollview with all available matches. But when I make a match it does not find any matches. Any idea what messed up?

public void RefreshRoomList() { ClearRoomList(); networkManager.matchMaker.ListMatches(0, 20, "", true, 0, 0, OnMatchList); status.text = "Loading..."; }

 public void OnMatchList(bool succes,string extendedInfo,List<MatchInfoSnapshot> matchList)
 {
     
     status.text = "";
     if(!succes || matchList == null)
     {
         status.text = "Couldn't get room list. That is all we know";
         return;
     }
    

     foreach (MatchInfoSnapshot match in matchList)
     {
         GameObject roomListItemGO = Instantiate(roomListItemPrefab);
         roomListItemGO.transform.SetParent(roomListParent);

         RoomListItem roomListItem = roomListItemGO.GetComponent<RoomListItem>();
         if(roomListItem != null)
         {
             roomListItem.Setup(match, JoinRoom);
         }

         roomList.Add(roomListItemGO);
     }

     if (roomList.Count == 0)
     {
         status.text = "No room at the moment, make your own room!, it is free!!!";
     }
     

     

 }
