Well, I finally resorted to this.
I have little to no idea about linux and thought I could set up a small plex server simply by following instructions. I installed OMV6 on an old laptop, OS on a 32GB SD card, docker on a 120GB SSD inside the laptop and the media files on a 1TB HDD via USB.
Everything was installed and working properly (sonarr, radarr, bazarr, torrent client and plex), I disable the handle lid switch so the laptop doesn't turn off when I close the lid aaaaaaaaand now I can't access the web GUI.
Everything else however, works perfectly. I can access all the docker containers and they're working fine, I can ping the machine and access via Windows network folders.
I've looked over the internet and none of the solutions suggested help me. I'm not sure neither how to check logs of what happens when trying to access the web GUI.
My apologies beforehand for my utter ignorance here, any advice is greatly appreciated.
