I deployed a basic service in my kubernetes cluster. I handle routing using this Ingress:

---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: owncloud
spec:
  rules:
    - host: example.com
      http:
        paths:
          - backend:
              serviceName: owncloud
              servicePort: 80

I generated a kubernetes secret in default namespace using a generated key and certificate. I named it example-tls and add it to the Ingress config under spec:

tls:
- secretName: example-tls
  hosts: 
    - example.com  

When I GET the service using https (curl -k https://example.com), it times out:

curl: (7) Failed to connect to example.com port 443: Connection timed out

It works using http.

What's possibly wrong here?

Here is the describe output of the concerned ingress:

Name:             owncloud
Namespace:        default
Address:
Default backend:  default-http-backend:80 (<none>)
Rules:

  ----                      ----  --------

                               owncloud:80 (10.40.0.4:80)
