Вчера у моего сайта протух SSL-сертификат, а Certbot не хочет его автоматически обновлять

Пробую обновить через
sudo certbot renew - вылетает по таймауту, Let's Encrypt не может достучаться до сайта, по-видимому, но сам сайт работает, проверял.

Кто сталкивался с подобным? В чём может быть проблема? Куда копать?
UPD: у меня есть предположение, что Nginx редиректит все запросы с 80 порта на 443 и поэтому директория
.well-known/acme-challengeнедоступна извне
