      The nextcloud module supports `nginx` as reverse-proxy by default and doesn't
      support other reverse-proxies officially.

      However it's possible to use an alternative reverse-proxy by

        * disabling nginx
        * setting `listen.owner` & `listen.group` in the phpfpm-pool to a different value

      Further details about this can be found in the `Nextcloud`-section of the NixOS-manual
      (which can be openend e.g. by running `nixos-help`).
