Plex alternative: Jellyfin installation guide on WD NAS

I also tried @dorz5 suggestion on my WDEx2Ultra on OS5 and the installation seems to work (no error message and it is running in Docker) but I cannot access to the Jellyfin admin webpage (http://my_internal_ip:8096). Am I missing something ? Thanks !
