Исключить пути прокси не работает

Я пытаюсь настроить обратный прокси для сайта WordPress. Проблема в том, что я пытаюсь исключить пути API WordPress Restraction и XML-файлы, но безуспешно. Правила исключения для wp-admin, wp-includes и других работают. Просто не могу заставить /wp-json/ и.xml исключать на работу.

<IfModule mod_ssl.c>
  <VirtualHost *:443>
    # The ServerName directive sets the request scheme, hostname and port that
    # the server uses to identify itself. This is used when creating
    # redirection URLs. In the context of virtual hosts, the ServerName
    # specifies what hostname must appear in the request's Host: header to
    # match this virtual host. For the default virtual host (this file) this
    # value is not decisive as it is used as a last resort host regardless.
    # However, you must set it for any further virtual host explicitly.
