Office365-rest-python-client: Подключение к Sharepoint

Я хочу размещать файлы этому простому примеру :

from office365.sharepoint.client_context import ClientContext

settings = {
    'url': 'https://*****.sharepoint.com/sites/*****',
    'user_credentials': {
        'username': '*****@gmail.com',
        'password': '*****',
    },
}

ctx = ClientContext(settings["url"]).with_user_credentials(settings.get('user_credentials').get('username'),
                                                           settings.get('user_credentials').get('password'))

web = ctx.web.get().execute_query()
print(web.properties["Url"])

что дает мне ошибку:

Любые идеи? Это не похоже на проблему аутентификации.
