Can't find MinimsSrver

[MrBlond]

Use case:
I want to use MinimServer as a DNLA mediaserver in my homenetwork, my primary use case is to expose the audio files from my NAS in the WIIM app to stream music to my WIIM players around the house.

Problem:
The problem I have is i am unable to discover MinimServer (or any DLNA mediaserver) in the WIIM app or mconnect app on my phone.

Current setup
I am using a wired NUC as my homelab with ESXI installed on it. One of these virtual machines runs Unbuntu Server 20.04.6 LTS and is my homelab. On that Ubuntu server i am running a docker setup with various applications, and i recently added the MinimServer container to my docker-compose file. As part of the docker script I made sure to include network_mode : host to ensure it can be discovered in the network.

I am able to browse to MinimServer webpage and there I can activate the license. For the rest there is nothing i can so as there are not a lot of settings to try, so not sure if MinimServer is able to find my media and works correctly.

Here is my docker-compose script:

minimserver:
image: minimworld/minimserver:2.2
container_name: minimserver
network_mode: host
environment:
- PUID=1000
- PGID=1000
- TZ=Europe/Amsterdam
volumes:
- /home/mrblond/docker/minimserver:/config
- /home/mrblond/data/nas_media/Music:/Music:ro
restart: unless-stopped

Where next?
Despite all these efforts i am unable to get MinimServer discovered. I can browse the the MinimServer url from any device in the network, but it is not discovered as a DNLA source unfortunately.

As a test I enabled DNLA from my Win11 machine and those files were immediately discovered by my WIIM application and by my mconnect app on my phone.

With the ease through wich Win11 DNLA source was discovered by my applications u thought there might be something in Ubuntu I need to add / change to make MinimServer discoverable in my network from that machine, but not really sure. Any suggestions where to look next to fix this issue?
