Configuration with SSL cert and termination at ELB (both 443 and 80 go to 80)

kind: Service
apiVersion: v1
metadata:
  name: ingress-nginx
  namespace: kube-system
  labels:
    k8s-addon: ingress-nginx.addons.k8s.io
  annotations:
    service.beta.kubernetes.io/aws-load-balancer-ssl-cert: "arn:aws:acm..." #arn to the certificate
    service.beta.kubernetes.io/aws-load-balancer-backend-protocol: "tcp"
    service.beta.kubernetes.io/aws-load-balancer-proxy-protocol: "*"
    service.beta.kubernetes.io/aws-load-balancer-ssl-ports: '443'
spec:
  type: LoadBalancer
  selector:
    app: ingress-nginx
  ports:
  - name: http
    port: 80
    targetPort: 80
  - name: https
    port: 443
    targetPort: 80 #all goes to 80

After applying above configuration, i'm not getting ELB dns or IP.

ubuntu@ip-172-31-47-72:~$ kubectl get svc ingress-nginx -n kube-system
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
ingress-nginx LoadBalancer 10.233.21.175 80:31342/TCP,443:30926/TCP 1m

How exactly kubectl/kubetnetes api connect to AWS?

service.beta.kubernetes.io/aws-load-balancer-internal: "0.0.0.0/0" is also needed if you are using a private ELB/topology
