Config.php Vs domains.config.php

Nextcloud version 24
UBUNTU 22.04
APACHE NGINX / HESTIA PANEL
PHP 8,1

trying to set up multiple trusted domains, i’ve chosen to create a domains.config.php file with:

$CONFIG[‘trusted_domains’] = array (
0 => ‘cloud.domain1.com’,
1 => ‘cloud.domain2.com’,

as in [Howto] Individual themes per domain - #6 by HeisenbergDo

from there, what should be left in config.php about trusted domains?

this is where i’m at . .
trying theming for domains

CONFIG.PHP

<?php
$CONFIG = array (
  'instanceid' => '---',
  'passwordsalt' => '--',
  'secret' => '---',
  'trusted_domains' => 
  array (
   0 => 'localhost',
   1 => 'domain0.net',
   2 => '111.222.333.44',
   4 => 'domain1.net',
   ),
   . . .

DOMAINS.CONFIG.PHP

<?php
    $CONFIG['trusted_domains'] = array (
    0 => 'domain0.net',
    1 => 'domain1.net'
);
if (isset($_SERVER['HTTP_HOST'])) {
    switch ($_SERVER['HTTP_HOST']) {
        case 'domain0.net':
            $CONFIG['theme']='domain0.net';
            $CONFIG['mail_from_address'] = 'address';
            $CONFIG['mail_domain'] = 'domain0.net';
            break;
        case 'domain1.net':
            $CONFIG['theme']='domain1.net';
            $CONFIG['mail_from_address'] = 'address';
            $CONFIG['mail_domain'] = 'domain1.net';
            break;
    }
}
