Подключение к Google calendar api на python

Не могу настроить доступ к API календаря Google с помощью python с сервера unix.

Пробовал использовать этот маунуал https://developers.google.com/calendar/api/quickstart/python. На данный момент я запускаю quickstart.py и получаю в консоли

Please visit this URL to authorize this application: https://accounts.google.com/o/oauth2/auth?response_type=code&client_id=99236485634896-kkavoaib8mp8ert4eri2d5v6gicfln14i0k.apps.googleusercontent.com&redirect_uri=http%3A%2F%2Flocalhost%3A42403%2F&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fcalendar&state=XEqxqNSDNKfksdfgwUXw24JjK4EzA4G&access_type=offline

При переходе по ссылке я вижу экран авторизации Google, выбираю аккаунт, разрешаю доступ, после чего меня перенаправляет на ссылку http://localhost:42403/?state=XEkxqN2KMDSgXknqUXw24JjK4EzA4G&code=4/2AbUR2VOHwy3nuCXdumqaJejyAb8F0N7LXQ2JA48EGgtuzCm64 uNc YJRb7wfTLgnVSA1C8g&scope=https://www.googleapis.com/auth/calendar и я вижу в браузере "Не удается получить доступ к сайту".

Помогите разобраться - что не так и как поправить чтобы подключиться к апи?
