Port 1883 blocked by NSX-T Edge firewall (DevOps to open on Monday).
Temporary solution: EMQX WebSocket listener (8083) via nginx-ingress.
- Service emqx-ws: selector app=emqx, port 8083
- Ingress emqx-mqtt-websocket: iot.kube5s.ru/mqtt → emqx-ws:8083
- pathType: Exact (prevents trailing slash redirect breaking WS handshake)
- ssl-redirect: false (IoT devices cannot follow HTTP 301 redirects)
- DNS A record iot.kube5s.ru → 185.247.187.147 created by user
Tested: Connected rc=0 via paho-mqtt WebSocket from inside cluster.
