логи здесь застревают... он должен продолжить рендеринг макета тире, но почему? кажется, моя аутентификация прошла правильно, но обратные вызовы не работают?? в чем может быть проблема помогите пожалуйста. пытаюсь развернуть это приложение, но на странице просто отображается «Загрузка...» в верхнем левом углу без рендеринга HTML
