Пустая страница Nginx 1.10 Wordpress PHP7.0-FPM

Я искал часами. Я нашел так много похожих случаев и не могу понять, почему мой не подходит. Когда я перехожу на свой веб-адрес, я получал ошибку 502 Bad Gateway. Теперь с текущими настройками это просто пустая страница. Я предполагаю, что файл не может быть найден, но я не смог найти никаких ошибок или чего-то пропавшего.

Я использую Ubuntu 16.04 LTS, Nginx 1.10, PHP 7.0 FPM, MySQL. Мне нужно поделиться чем-нибудь еще? Спасибо всем за помощь.
