Это новый сервер, работающий на Ubuntu 20.04, и мне так и не удалось отобразить веб-страницу. Я настоящий новичок, поэтому вопрос может быть глупым. Я просмотрел другие существующие темы, но не смог разобраться со своей проблемой. Дайте мне знать, если понадобится что-то еще.

Как вы можете видеть в отчете curl, перенаправление на протокол https инициируется пользователем Phusion. Тогда nginx не может обработать запрос, потому что нет серверов, которые прослушивают порт 443.
