Nextcloud URL points to OMV5 Control Panel

[/details]

Nextcloud version (eg, 20.0.5): Should be latest
Operating system and version (eg, Ubuntu 20.04): Raspian Lite
Apache or nginx version (eg, Apache 2.4.25): NGINX 2021/09/09
PHP version (eg, 7.4): replace me

The issue you are facing:
I installed nextcloud + nextclouddb+ swag over a stack in portainer on my OMV5 on my RPi4
I got a duckdns url and duckdns running in said portainer
No logs show any errors.
When I go to myurl.duckdns.org I come out at the openmediavault control panel
When I go to nextcloud.myurl.duckdns.org (I’m using the subdomain config in proxy-confs for swag), I come out at the openmediavault control panel again
I have not managed to reach the nextcloud welcome page so far and I’ve been at it all day
Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Enter nextcloud.myurl.duckdns.org
  2. Come out at the openmediavault controlpanel
