google cloud platform - Kubernetes Ingress (GCE) keeps returning 502 error

Question

I am trying to setup an Ingress in GCE Kubernetes. But when I visit the IP address and path combination defined in the Ingress, I keep getting the following 502 error:

Here is what I get when I run: kubectl describe ing --namespace dpl-staging

Name:           dpl-identity

I think the problem is dpl-identity:4000 (<none>). Shouldn't I see the IP address of the dpl-identity service instead of <none>?

Here is my service description: kubectl describe svc --namespace dpl-staging

Name:           dpl-identity
Namespace:      dpl-staging
Labels:         app=dpl-identity

Also, here is the result of executing: kubectl describe ep -n dpl-staging dpl-identity
