Ingress GCE is not working due to health check being failed for backend service

[yugandharreddy1]

We see than when we install with NIGINX everything is working fine but then changing to ingress GCE with below annotations its creating 2 services one is healthy and other is unhealthy.

ingress:
  annotations:
    - kubernetes.io/ingress.class: gce
    - kubernetes.io/ingress.allow-http: "true"
    - gcp.ingress.kubernetes.io/target-type: ip

below are the services which are being created

by default the health check is checking on HTTP 80 and when i change it to TCP 3128 its becoming healthy and i was able to access the ingress URL.

i dont know from which service readiness probe i am getting the healthcheck created as below i didnt mention anywhere HTTP 80
