Liveness and readiness probe connection refused

Question

I keep getting this error when I try to setup liveness & readiness prob for my awx_web container

Liveness probe failed: Get http://POD_IP:8052/: dial tcp POD_IP:8052: connect: connection refused

Liveness & Readiness section in my deployment for the container awx_web

          ports:
          - name: http
            containerPort: 8052 # the port of the container awx_web
            protocol: TCP
          livenessProbe:
            httpGet:
              path: /
              port: 8052
            initialDelaySeconds: 5
            periodSeconds: 5
          readinessProbe:
            httpGet:
              path: /
              port: 8052
            initialDelaySeconds: 5
            periodSeconds: 5

if I test if the port 8052 is open or not from another pod in the same namespace as the pod that contains the container awx_web or if I test using a container deployed in the same pod as the container awx_web i get this (port is open)

/ # nc -vz POD_IP 8052
POD_IP  (POD_IP :8052) open

I get the same result (port 8052 is open) if I use netcat (nc) from the worker node where pod containing the container awx_web is deployed.

for info I use a NodePort service that redirect traffic to that container (awx_web)

type: NodePort
ports:
- name: http
  port: 80
  targetPort: 8052
  nodePort: 30100

In my case this issue has occurred because I've configured the backend application host as localhost. The issue is resolved when I changed the host value to 0.0.0.0 inside my app properties.

Use the latest built docker image after making this change.
