I found one that was using port 1900 but was not showing in the port mapping of the docker page.
Turning this off didn't work at first, but then I turned everything off one by one and it ended up working when I also turned off Jellyfin. Now I'm not sure if Jellyfin is really related because it is in host mode, not using port 1900 and now both are runing at the same time.
anyways, turning off some dockers did end up making it work!
Thanks!
EDIT: Somehow it really looks related to jellyfin, I am onle able to start it if jellyfin is not running, but once it's started I can start jellyfin after without any issues.
