PROGRESS LOG:
1. Created docker-compose.yml with Traefik (port 80, Docker provider, proxy network) and NCA Toolkit (ghcr.io/ncomputing/nca-toolkit:latest) services.
2. Initial attempt to bring up stack failed due to Docker daemon missing on host.
3. Repaired Docker installation; dockerd running; Compose and client working.
4. Stack start failed: cannot pull ghcr.io/ncomputing/nca-toolkit:latest (permission denied or image private).
5. Noted NCA Toolkit + Traefik should be set up inside VM 112 (n8n), not host—attempts to access 112 from Proxmox CLI failed (timeout); cannot enter 112 from current CLI session.
6. Next steps: check/boot/access VM 112 in Proxmox UI or get SSH IP for n8n VM.
Will update when VM 112 access is restored and NCA Toolkit is set up inside correctly.
