Невозможно подключиться к хосту api.telegram.org:443 SSL:default ⇐ Python

[Anonymous]

Я пишу телеграмм-бота на фреймворке aiogram. Когда я запускал, все было хорошо, но сегодня я получаю сообщение об ошибке:Cannot connect to host api.telegram.org:443 ssl:default Я не знаю, в чем проблема.

Я использую Ubuntu 20.04.2 LTS

Вот полная ошибка
