LobbyService (401) HTTP/1.1 401 Unauthorized

Hello.
Developed using Lobby from Unity Gaming Services.

Running the lobby function in the Editor results in an “HTTP/1.1 401 Unauthorized” error.
Same as the thread below, only after exiting play mode and running it again.

My current version is using Unity 2022.3.3f1, Lobby 1.1.0

Is there an established solution to the content of this thread?

I tried various cases, but I was able to reproduce it even in a simple case.
I will paste the source code for one case.

    private async void OnEnable()
    {
        joinedLobby = null;
        await SignIn();
        joinedLobby = await CreateLobbyAsync("test lobby", 2);
        Debug.Log($" Id:{joinedLobby.Id}, Name:{joinedLobby.Name}");
    }

    private async Task<Lobby> CreateLobbyAsync(string lobbyName, int maxPlayers)
    {
        return await Lobbies.Instance.CreateLobbyAsync(lobbyName, maxPlayers);
    }

    private async Task SignIn()
    {
        await UnityServices.InitializeAsync();
        await AuthenticationService.Instance.SignInAnonymouslyAsync();
    }

    void OnDisable()
    {
        if (AuthenticationService.Instance.IsSignedIn)
            AuthenticationService.Instance.SignOut(true);
    }

By the way, the phenomenon is reproduced regardless of whether SignOut processing is performed or not.
When I rerun it, an error occurs at CreateLobbyAsync()

I have a similar problem when trying to Query for a lobby list, but I still haven’t found a solution either.

I have the same problem but only sometimes… It’s annoying
