Kong Connection Issues with EMQX

[rakeshreddyrg09]

Hi team,
I have installed Kong in my EKS cluster.
here is my proxy configuration

proxy:
        streamPorts:
          # MQTT SSL Port
          - protocol: TCP
            containerPort: 1883
            servicePort: 1883
          # MQTT SSL Port
          - protocol: TCP
            containerPort: 8883
            servicePort: 8883
        tls:
          containerPort: 8000

TCPIngress

apiVersion: configuration.konghq.com/v1beta1
kind: TCPIngress
metadata:
  name: mqttingress
  namespace: iotcore
  annotations:
    kubernetes.io/ingress.class: "kong"
spec:
  rules:
    - port: 1883 # MQTT port
      backend:
        serviceName: emqx
        servicePort: 1883
    - port: 8883 # MQTT SSL port
      backend:
        serviceName: emqx
        servicePort: 8883

here when I try to run this

mqttx pub \
  --hostname mqtt.iot-test.org.com \
  --port 1883 \
  --topic devices \
  --message "{\"deviceId\":16,\"value\":40.1,\"region\":\"EMEA\",\"timestamp\":1482236627236}" \
  --username 'admin' \
  --password 'public'

below is the ticket raised for the same issue with mqttx community
emqx/MQTTX#1726

mqttx is unable to send the message and I don't see any logs in Kong.
Traffic is coming in when I use curl with http end point, but not for the mqttx with tcp endpoint
can anyone help me here
