I'm setting up a Janusgraph instance with Kubernetes on GKE and my internal load balancer works fine. However, when using Ingress to expose an https endpoint, I can't resolve the following status:

All backend services are in UNHEALTHY state

My Service configuration is:

apiVersion: v1
kind: Service
metadata:
  creationTimestamp: "2020-04-24T05:53:47Z"
  labels:

    release: janusgraph
  sessionAffinity: None
  type: LoadBalancer
status:
  loadBalancer:
    ingress:
    - ip: 35.236.228.15

My Ingress configuration is:

apiVersion: extensions/v1beta1
kind: Ingress

Thanks for your help in advance.
