Error installing NextCloud on (at least) UCS 4.4 (now without sensitive information publicised)

[kfk]

Hello,

I have been trying to install NextCloud on my instance of UCS (4.4-9 errata1259)

I do the install edit the config.php to look like this:

<?php
$CONFIG = array (
  'passwordsalt' => 'REDACTED',
  'secret' => 'REDACTED',
  'trusted_domains' => 
  array (
    0 => 'ucs-9592.MYDOMAIN.dk',
    1 => '1.1.1.1',
    2 => 'MYDOMAIN.dk', # this is the actual edit
  ),
  'datadirectory' => '/var/lib/univention-appcenter/apps/nextcloud/data/nextcloud-data',
  'dbtype' => 'pgsql',
  'version' => '23.0.5.1',
  'overwrite.cli.url' => 'https://ucs-9592.MYDOMAIN.dk/nextcloud',
  'dbname' => 'nextcloud',
  'dbhost' => '172.17.42.1:5432',
  'dbport' => '',
  'dbtableprefix' => 'oc_',
  'dbuser' => 'nextcloud',
  'dbpassword' => 'REDACTED',
  'installed' => true,
  'instanceid' => 'REDACTED',
  'updatechecker' => false,
  'upgrade.disable-web' => true,
  'memcache.local' => '\\OC\\Memcache\\APCu',
  'memcache.distributed' => '\\OC\\Memcache\\APCu',
  'overwriteprotocol' => 'https',
  'overwritewbroot' => '/nextcloud',
  'htaccess.RewriteBase' => '/nextcloud',
  'ldapProviderFactory' => 'OCA\\User_LDAP\\LDAPProviderFactory',
  'trusted_proxies' => 
  array (
    0 => '2.2.2.2',
  ),
);

and get an error like this:

I tried doing a fresh install to test out if it was something I had tinkered with but got the same results…

Please advice

update:
I just tried using the original config file:

  'trusted_domains' => 
  array (
    0 => 'ucs-9592.MYDOMAIN.dk',
    1 => '1.1.1.1',
  ),

and like this I can access ucs-9592.MYDOMAIN.dk/nextcloud but obviously not MYDOMAIN.dk/nextcloud which is what I’d like the users to be able to do…

Turns out it works better when done “the univention way”, go figure…
