http страницы сайта отдают код 200 хотя настроен редирект на https

До сих пор не смог решить проблему.
.htaccess сайта выглядит так:

Пробовал всевозможные варианты вставок из темы https://ru.wordpress.org/support/topic/%d0%bf%d1%80%d0%be%d0%b1%d0%bb%d0%b5%d0%bc%d0%b0-%d1%81-%d1%80%d0%b5%d0%b4%d0%b8%d1%80%d0%b5%d0%ba%d1%82%d0%be%d0%bc-%d0%bd%d0%b0-https/ но безуспешно. Сайт всегда либо вообще переставал работать, либо все время переадресовывался на главную.
