Статус 403 при вызове WordPress на nginx без префикса протокола

Когда я звоню в свой интернет-магазин в Chrome или любом другом веб-браузере без префикса https, я получаю статус 403. Я не знаю почему. Ошибка появляется, так как я установил и удалил плагин колибри от wpmudev.

Вот моя конфа:

Я использую WordPress с woocommerce на экземпляре Ubuntu 14.04 aws ec2. Дополнительно сайт защищен ssl. Плагин NGINX Helper присутствует и активен, но в этой ситуации его не трогали.

Если возможно, дайте какое-нибудь объяснение, чтобы я мог узнать что-то об этой проблеме.
