Do Ingress work with ClusterIP services?

I installed some services and applications to check SSL completion. I didn’t have any problems with services LoadBalancerand NodePortas a backend, but it didn’t work with the service at all ClusterIP.

Although the Ingress backend is described as healthy, I get an HTTP error that does not come from my application.

$ kubectl describe ing nginx-cluster-ssl-ingress
Name:           nginx-cluster-ssl-ingress
Namespace:      default
Address:        X.X.X.X
Default backend:    nginx-cluster-svc:80 (...)
TLS:
  ssl-certificate terminates

  27m       27m     1   {loadbalancer-controller }          Normal      CREATE  ip: X.X.X.X

The HTTP error is as follows:

$ curl http://X.X.X.X/
default backend - 404%

My question is pretty simple: should it work with ClusterIP services? If it should be more or less written in the documentation, where should I look for a solution to this problem?

Thank!
