HTTPS Redirect middleware with Google Kubernetes Engine

Traefik Traefik v2

I'm trying to test and implement Traefik's https redirect feature in my kubernetes cluster per Traefik's documentation: https://docs.traefik.io/middlewares/overview/. Here's the definition of the Middleware and IngressRoute :

apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
  name: ingressroutetls
  namespace: default
spec:
  entryPoints:
    - web
    - websecure
  routes:
  - match: Host(`your.domain.name`) && Host(`www.your.domain.name`)
    kind: Rule
    services:
    - name: traefik-dashboard
      port: 8080
    middlewares:
      - name: redirectscheme
  tls:
    secretName: cloud-tls


apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
metadata:
  name: redirectscheme
spec:
  redirectScheme:
    scheme: https

However, https ://your.domain.name works and http ://your.domain.name gives me a 404 page not found . Does anyone know what have I misconfigured ?
