Порт HTTPS веб-сервера Apache перенаправляет на HTTP с портом 443

На работе я установил Mediawiki (последнюю версию) на веб-сервере Apache 2.4.6 с PHP 5. Все работает нормально, когда я хочу получить доступ к страницам вики локально и я настраиваю имя хоста в Mediawiki.

$wgServer = https://en.wiki.example.com. 

Теперь, когда я очищаю эту конфигурацию имени хоста в Mediawik, он должен получить имя хоста, которое получает веб-сервер. Это случается, но формат имени хоста

http://en.wiki.example.com:443 

который является неправильным URL-адресом (из-за смешивания HTTP с HTTPS).

Я думаю, что это проблема Apache, потому что, когда я пытаюсь перейти к

https://en.wiki.example.com/wiki 

он перенаправляет на

http://en.wiki.example.com:443/wiki/index.php/Main_Page

и я получаю ошибку неверного запроса. Завершающая косая черта после вики не имеет никакого эффекта.

Поскольку таблица стилей и расположение скриптов разрешены, я вижу один и тот же шаблон URL (

http://en.wiki.example.com:443/wiki/load.php....

). То же самое и с переменными URL в Mediawiki. Кто-нибудь видит, что я здесь делаю не так? Заранее спасибо. Также я добавил подчеркивание, чтобы удалить форматирование ссылок в этом вопросе.

Изменить: обновленные URL-адреса.
