login not working for me :/

Hi guys! Using code from example, but its not working :/

I don't get any callback and code stuck in while cycle

` var user = "*";
var pass = "";

        string authCode = null, twoFactorAuth = null;

        // create our steamclient instance
        var steamClient = new SteamClient();
        // create the callback manager which will route callbacks to function calls
        var manager = new CallbackManager(steamClient);

        // get the steamuser handler, which is used for logging on after successfully connecting
        var steamUser = steamClient.GetHandler<SteamUser>();

        // register a few callbacks we're interested in
        // these are registered upon creation to a callback manager, which will then route the callbacks
        // to the functions specified
        manager.Subscribe<SteamClient.ConnectedCallback>(OnConnected);
        manager.Subscribe<SteamClient.DisconnectedCallback>(OnDisconnected);

        manager.Subscribe<SteamUser.LoggedOnCallback>(OnLoggedOn);
        manager.Subscribe<SteamUser.LoggedOffCallback>(OnLoggedOff);

        // this callback is triggered when the steam servers wish for the client to store the sentry file
        manager.Subscribe<SteamUser.UpdateMachineAuthCallback>(OnMachineAuth);

        var isRunning = true;

        Console.WriteLine("Connecting to Steam...");

        // initiate the connection
        steamClient.Connect();

        Console.WriteLine();

        // create our callback handling loop
        while (isRunning)
        {
            // in order for the callbacks to get routed, they need to be handled by the manager
            manager.RunWaitCallbacks(TimeSpan.FromSeconds(1));
        }

        {

                AuthCode = authCode,

                // if the account is using 2-factor auth, we'll provide the two factor code instead

What im doing wrong? Pls help me, its my first time working with this library :(
