Help installing LMS - App stuck on 'Deploying'

Hi
Really hoping someone can give me some pointers here please?
New installation of Scale v22. I have emby and netdata running but Lyrion music server refuses to deploy. - it’s stuck.

Docker image: ghcr[dot]io/lyrion/music-server:latest
Container : music
Host path mnt media_music
port set to 15000 (9000 in use)
ACL permissions set to full control
it comes up in installed applications, but is stuck on Deploy.
any suggestions?
Thanks in advance
