 ## Troubleshooting
 - **S3 errors**: Verify credentials in `/app/data/config/s3.env`; check connectivity using `aws s3 ls --endpoint-url ...` from a trusted host.
+- **Startup issues**: Inspect `/app/data/logs/startup.log` (also mirrored to `cloudron logs`) for rendered configuration and error messages.
 - **Museum not starting**: Inspect `/app/data/museum/configurations/local.yaml` for syntax issues; delete to regenerate.
 - **Frontend stale after update**: Restart the app—the startup script re-syncs static assets on each boot.
 - **OIDC issues**: Confirm the callback URL `/api/v1/session/callback` is allowed in the Cloudron SSO client configuration.
