2 Nextcloud instance behind pfsense/HAProxy

Aphid77

I am trying to install 2 nextcloud instances (business and private) via docker AIO on a proxmox server behind a pfsense firewall. The proxy is done via HAProxy on pfsense. Both instances are installed on their own virtual machine and have their own fixed ip address.
I use this docker-compose file for the installation

services:
    all-in-one:
        image: 'nextcloud/all-in-one:latest'
        volumes:
            - '/var/run/docker.sock:/var/run/docker.sock:ro'
            - 'nextcloud_aio_mastercontainer:/mnt/docker-aio-config'
        ports:
            - '8843:8080'
        environment:
          - APACHE_PORT=11000
          - APACHE_IP_BINDING=0.0.0.0
          - NEXTCLOUD_DATADIR=/mnt/srv/ncdata
          - SKIP_DOMAIN_VALIDATION=true
        restart: always
        container_name: nextcloud-aio-mastercontainer
        init: true
volumes: # If you want to store the data on a different drive, see https://github.com/nextcloud/all-in-one#how-to-store-the-filesinstallation-on-a-separate-drive
    nextcloud_aio_mastercontainer:
      name: nextcloud_aio_mastercontainer # This line is not allowed to be changed as otherwise the built-in backup solution will not work

They use the same frontend in HAProxy and have their own backend in which the difference between them is their ip address and port.
The first instance is reachable without any problem, it also gets a letsencrypt certificate from pfsense but the second instance is my problem child. The installation via docker-compose goes smoothly, can log into the AIO web page without any problem, select containers and they all come online.
However now when I try to reach this nextcloud-instance via the url I keep getting error 503 - Service Unavailable but I do get the correct letsencrypt certificate for this subdomain.
Is there anyone who has a similar setup and can steer me in the right direction to get both instances working.

This mostly means, that HAproxy get nothing back from the backend server.
You have to investigate, why it doesn't respond.
