Can't connect to Nextcloud | Gateway Timeout

Hey I solved It by adding in my nextcloud configuration this in /etc/apache2/apache2.conf:

ServerName my.domain.org

Also in /var/www/nextcloud/config/config.php

  'trusted_domains' =>
  array (
    0 => '192.168.1.13:8282',
    1 => 'my.domain.org',
  ),
  'trusted_proxies' =>
  array (
    0 => '172.28.0.0/16',
  ),

and in my traefik docker-compose.yml:

    command:
      - "--providers.docker.network=traefik"
