Troubleshooting

Movie grabbed but not imported

Check queue: curl -s "$RADARR/api/v3/queue" -H "X-Api-Key: $RADARR_KEY"
Verify /volume1/data mount and permissions

SABnzbd not receiving jobs

Check download clients: Settings → Download Clients → SABnzbd → Test
Confirm SABnzbd is running: docker ps | grep sabnzbd

Torrent grabbed before 2-hour wait

Verify delay profile: bypassIfHighestQuality must be false
