Notes

If you plan on using a reverse proxy, you will have to define your domain or subdomain as trusted proxy domain.

The relevant nextcloud configuration file to define this is located at:

# linuxserver image
/<your-volume-path>/config/www/nextcloud/config/config.php

# official nextcloud image
/<your-volume-path>/nextcloud/app/config/

Adjust the PHP file and put in your subdomains at trusted_domains as well as trusted proxy IPs at trusted_proxies. Also set overwriteprotocol to https and may define a maintenance window via maintenance_window_start.

Something like this:

<?php
$CONFIG = array (
  ...
  'trusted_domains' => 
  array (
    0 => 'nextcloud.example.com',
    1 => 'nextcloud.anotherdomain.com',
  ),
  'trusted_proxies' => 
  array (
    0 => ['10.0.0.0/8'],
    1 => ['172.16.0.0/12'],
    2 => ['192.168.0.0/16'],
  ),
  'overwriteprotocol' => 'https',
  'maintenance_window_start' => 1,
  ...
);
