Update Troubleshooting
"Control Plane unreachable" warning
The Atrium instance can't reach the Control Plane at cp.atrium.sprocksystems.de.
Check:
- Outbound HTTPS connectivity:
curl -v https://cp.atrium.sprocksystems.de/healthfrom the server. - DNS resolution:
dig cp.atrium.sprocksystems.de. - Proxy/firewall: Ensure outbound HTTPS to this domain is allowed.
Impact: The instance continues to operate normally during the grace period (default: 30 days). No updates are available until connectivity is restored.
Update available but not applying (notify mode)
In notify mode, updates require manual approval:
- Check the admin dashboard for the update notification.
- Review the version information and release notes.
- Click Apply Update.
If you don't see the notification, check that you're logged in as a Tenant-Admin — only Tenant-Admins can approve updates.
Update failed — automatic rollback
If the Update Agent detects that containers are unhealthy after applying an update, it automatically rolls back to the previous version:
- The previous Docker Compose file is restored from a local backup.
docker compose up -druns with the previous configuration.- The failure is reported to the Control Plane on the next check-in.
After a rollback:
- Check the Update Agent logs:
docker logs atrium-updater. - Common causes: disk space exhaustion (images couldn't be pulled fully), database migration failure, or a container crash loop.
- The failed update won't be retried automatically. Resolve the underlying issue, then trigger the update again.
