traefik-multi-network-missing-label-routes-wrong-ip
When a container belongs to multiple Docker networks and lacks the traefik.docker.network label, Traefik arbitrarily picks one network IP — often the wrong one — causing backend timeouts. Fix: add traefik.docker.network=<intended-network> label to the container, then recreate it. Affected container: researchclaw on mcp-global-network + graphiti_oracle-internal; Traefik was routing to the unreachable graphiti_oracle-internal IP.
