Calibre docker on Synology NAS

I cant get this docker to start. I have other linuxserver dockers running fine but this one seems to hang. Others have posted about this (on the unraid forum) but no one seems to have a solution. I’ve tried older builds but no change. Anyone else had this issue?

I used this docker command
docker create
-e PUID=1029
-e PGID=101
-e TZ=Pacific/Auckland
-p 8080:8080
-p 8081:8081
-v /volume1/apps/calibre:/config
–restart unless-stopped

Log looks ok to about here -
