Kong version ($ kong version)

Kong version: 3.1.1-alpine

Current Behavior

Hi,

I am trying to proxy web application hosted inside a VM via kong through TCP ingress on specific port.
Getting below error in kong logs.

**Error:--**
[error] 54#0: *22895 stream [lua] handler.lua:1067: before(): no Route found with those values while prereading client data, client: 127.0.0.1, server: 0.0.0.0:9000

kubernetes-ingress-controller:2.7.0
Kong version: 3.1.1-alpine

Thanks in advance for your help.

Expected Behavior

When I make the below api call on port 28080, the request should goto kong on port 9000, then kong should redirect the request to external mock-test.service:28080 (TCP) which is hosted in VM.
http://localhost:28080/

From one of the pod, when I am making call directly to mock-test.service:28080 (service), I am getting the response back, but only via kong, I am getting error as below.

**Error:--**
[error] 54#0: *22895 stream [lua] handler.lua:1067: before(): no Route found with those values while prereading client data, client: 127.0.0.1, server: 0.0.0.0:9000

Steps To Reproduce

1. In kong deployment, I had put the below configuration

- name: KONG_PROXY_LISTEN
   value: 0.0.0.0:8000,0.0.0.0:8443 ssl http2
- name: KONG_STREAM_LISTEN
   value: 0.0.0.0:9000

  ports:
        - containerPort: 9000
          name: stream9000
          protocol: TCP

2. In kong proxy service, I had put the below configuration

 - name: kong-stream9000
    port: 9000
    protocol: TCP
    targetPort: 9000

3. Created TCPIngress, KongIngress and Service below

---
apiVersion: configuration.konghq.com/v1beta1
kind: TCPIngress
metadata:
  annotations:
    kubernetes.io/ingress.class: kong
    konghq.com/strip-path: "true"
    konghq.com/preserve-host: "false"
  name: mock-dashboard-service-tcpingress
spec:
  rules:
  - port: 28080
    backend:
      serviceName: mock-dashboard-service
      servicePort: 28080
---
apiVersion: v1
kind: Service
metadata:
  name: mock-dashboard-service
spec:
  externalName: mock-test.service
  ports:
  - port: 28080
    protocol: TCP
    targetPort: 28080
  type: ExternalName

Anything else?

Hi @dsnr-coder
I meet the same problem, could you please have a help?
this is my config:
gateway config:

apiVersion: gateway.networking.k8s.io/v1
kind: Gateway
metadata:
  name: echo-example-gateway
  namespace: default
spec:
  gatewayClassName: kong
  listeners:
  - name: echo-example
    protocol: TCP
    port: 9000
    allowedRoutes:
      kinds:
      - kind: TCPRoute

tcproute config:

apiVersion: gateway.networking.k8s.io/v1alpha2
kind: TCPRoute
metadata:
  name: echo
spec:
  parentRefs:
  - name: echo-example-gateway
    sectionName: echo-example
  rules:
  - backendRefs:
    - name: echo
      port: 1025

the result is this:

2024/12/11 09:10:31 [info] 1111#0: *175745 client 10.62.109.72:51182 connected to 0.0.0.0:9000
