Redirect scheme does not seem to always work

Traefik Traefik v2

I have an IngressRoute setup:

---
apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
  name: landing-test-secure
  namespace: test
spec:
  entryPoints:
    - websecure
  routes:
    # Match is the rule corresponding to an underlying router.
    - match: Host(`site.test`, `www.site.test`)
      kind: Rule
      services:
        - name: landing-published
          port: 3000
      middlewares:
        - name: traefik-http@kubernetescrd
        - name: traefik-addwww@kubernetescrd
---

With the following middleware:

---
# Redirect to http
apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
metadata:
  name: http
spec:
  redirectScheme:
    scheme: http
    port: 80
---
# Add www
apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
metadata:
  name: addwww
spec:
  redirectRegex:
    regex: http(s?)://([^w]{3})(.*)
    replacement: http://www.${2}${3}
---

If I go to https://www.site.test I do not get redirected to http://www.site.test

However, if I go to https://site.test I do get redirected to http://www.site.test

It seems that the RedirectRegex middleware works, but RedirectScheme does not.

In the dashboard, I see that both middlewares are active on the route. On most other routes I have the exact same setup but in reverse (http -> https) and it works fine. For some reason when going the other way, it does not seem to work.

@davedray,

What does curl -v https://www.site.test give you?
