Какието проблемы с отправкой запросов requests. Как решить?

Я сделал телеграмм бота , который должен отправлять запрос на сайт и скачивать оттуда картинку,а затем отправлять в сообщения. Захотел залить на бесплатный хостинг https://www.pythonanywhere.com/ ,но при запуске столкнулся с такой проблемoй:
