Truenas Nextcloud goes to IP not Domain

Hey there,
im new to Nextcloud and Truenas.
My Setup:
Homeserver with Truenas Scale on it.
Ports 80 and 443 from Router to Nginx ports.
From Nginx to Nextcloud instance on Port 9001.

Nextcloud version: 28.0.2 from the Truenas Catalog

The problem is that the Domain goes to the Internal Ip at the moment and i can´t figure out why this is happening.
If i try it outside my network i get the Message:
Site not Found
The Site was not found on the server or is not permitted to be displayed.

In the app i can get to the login screen and if i try to Ligon i get an infinite loading circle.

‘overwritehost’ => ‘mydomain:9001’,
‘overwriteprotocol’ => ‘https’,
‘trusted_proxies’ =>
array (
0 => ‘’,
‘upgrade.disable-web’ => true,
‘passwordsalt’ => ‘',
‘secret’ => '
‘trusted_domains’ =>
array (
0 => ‘localhost’,
1 => ‘internal Ip’,
2 => ‘mydomain’,
‘datadirectory’ => ‘/var/www/html/data’,
‘dbtype’ => ‘pgsql’,
‘version’ => ‘’,
‘overwrite.cli.url’ => ‘https://mydomain’,
‘dbname’ => ‘nextcloud’,
‘dbhost’ => ‘nextcloud-postgres:5432’,
‘dbport’ => ‘’,

I tried other combinations of this config as well.
I tried everywhere where my domain is displayed alone and nothing worked.

Has anyone an idea whats wrong?

Add your domain there.

Hey there,
tried putting the Domain in there it still does not work.

If i put the local Truenas port into nginx I can go to my truenas via domain name.
Same with plex.

Only nextcloud doesn´t seem to work for some reason.

Maybe this might cause the issue.

Normally you call with http://truenas the truenas nginx page(s) and with http:/truenas/nextcloud the Nextcloud-instance.

So your /var/log/nginx/access_log should mention the reason, whether Nexctloud could be called and the nextcloud.log should mention, wthether the call using the hostname could read Nextcloud.

That may be the case if i Installed the Truechart version of Nextcloud.
Wich i tested but i cant realy get that one to Fuction properly.
I get errors every time i Install it and it refuses to Deploy.
If you have an indepth Guide for the Installation procedure of the Truechart version i would appreciate that.
(Yes i installed Traefik and the other dependency app when i tried that version)
