I installed Kubernetes NGINX Ingress in kubernetes cluster. When i am trying to access the micro service end via Ingress Controller its not working as expected

I am deploying on AWS Instance, i followed the documentation from here

I have two Spring boot application which has context path as /customer running on port 9000 and /prac running on port 8000 and third one is nginx running on port 80

I have executed these commands to create ingress controller of Type LoadBalancer

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/nginx-0.30.0/deploy/static/mandatory.yaml

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/nginx-0.30.0/deploy/static/provider/aws/service-l4.yaml
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/nginx-0.30.0/deploy/static/provider/aws/patch-configmap-l4.yaml

After installing ingress nginx, I have created ingress controller which is of type Loadbalancer.

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: practice-ingress
  namespace: practice
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /
spec: 
  rules:
  - host: kdhut.com
    http: 
      paths:
      - backend:
          serviceName: customer-service
          servicePort: 9090
        path: /customer
      - backend:
          serviceName: prac-service
          servicePort: 8000
        path: /prac
      - backend:
          serviceName: ngtest
          servicePort: 80
        path: /

I created Classic Load Balancer, but the load Balancer health check is not passing, health check i am pointing to port 80, but its showing out of service.

I tried to check with Cluster IP, but its show Empty response from the server, please help me on this.
