I created a Deployment, Service and an Ingress. Unfortunately, the ingress-nginx-controller pods are complaining that my Service does not have an Active Endpoint:
controller.go:920] Service "<namespace>/web-server" does not have any active Endpoint.

In the same namespace, I have more Service and Deployment resources, all of them work, except this one (+ another, see below).
# kubectl get endpoints -n <namespace>
NAME ENDPOINTS AGE
activemq 10.233.64.3:61613,10.233.64.3:8161,10.233.64.3:61616 + 1 more... 26d
content-backend 10.233.96.17:8080 26d
datastore3 10.233.96.16:8080 26d
web-server 74m
web-server-metrics 26d
As you can see, the selector/label are the same (web-server) in the Service as well as in the Deployment definition.
