Health check Failing

[caxefaizan]

I Have an application deployed whose service has the following ports

apiVersion: v1
kind: Service
metadata:
  name: app-ingress-svc
  namespace: app
spec:
  ports:
  - name: status-port
    port: 15021
    protocol: TCP
    targetPort: 15021
  - name: https
    port: 443
    protocol: TCP
    targetPort: 8443

I configured my INgress object as

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: app-ingress
  namespace: app
  annotations:
    kubernetes.io/ingress.class: azure/application-gateway
    appgw.ingress.kubernetes.io/use-private-ip: "true"
    appgw.ingress.kubernetes.io/backend-protocol: https
    appgw.ingress.kubernetes.io/health-probe-path: "/healthz/ready"
    appgw.ingress.kubernetes.io/health-probe-port: "15021"
spec:
  tls:
  - hosts:
      - example.net
      secretName: app-gateway-secret
  rules:
  - host: example.net
    http:
      paths:
      - path: /
        backend:
          service:
            name: app-ingress-svc
            port:
              number: 443
        pathType: Prefix

I have the AGIC add on depployed on my AKS cluster where the logs suggests

I0712 12:49:58.547239       1 mutate_app_gateway.go:177] BEGIN AppGateway deployment

However, My health check is failing, where my pod has the http-get readiness check as

Readiness:  http-get http://:15021/healthz/ready delay=1s timeout=1s period=2s #success=1 #failure=30

But there is no annotation to support that unlike the AWS-ALB controller, where we can define alb.ingress.kubernetes.io/healthcheck-protocol: HTTP

I tried creating a custom probe

with the respectibe backend setting as

Am i doing anything wrong here?
