Troubleshooting

Can’t access services - Check containers are healthy: docker compose -f deploy/docker-compose.yml ps - Ports 8000/9090/3000 must be free

Grafana login fails - Ensure deploy/grafana/credentials/admin_password.txt is set - Restart Grafana: docker compose -f deploy/docker-compose.yml up -d grafana

Prometheus shows target down - API must expose /metrics; check http://localhost:8000/metrics - Network issues? Try host.docker.internal:8000 on macOS

Training not progressing - Reduce rounds; check participant registration and strategy - Inspect API logs for validation errors
