Вот мой nginx conf, я использую его для ssl, так как у меня есть лак на порту 80 apache на порту 8080 и nginx для лицензирования на 443 ssl.

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

}

http {

                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

Моя домашняя страница WordPress в бесконечном цикле.

ERR_TOO_MANY_REDIRECTS

остальная часть веб-сайта выглядит нормально, у меня есть облачная вспышка, а также сервер имен и кеширование. (все файлы cookie испортились, я думаю, потому что я не могу войти в wp-admin)

Я проверял использование сайта http://www.redirect-checker.org/ и сообщает, что обычные страницы имеют примерно 4 перенаправления и домашнюю страницу 19 (бесконечный цикл)

Есть идеи, как исправить?
