Traefik ingress - transport issue

Traefik Traefik v2
1

Hi,

I'm running Traefik on an AKS cluster, using ingressClassName: traefik to tell Traefik that it should be used.

Traefik is deployed via Helm, with a http -> https redirect. I have a ingress that looks like this:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: appname
  namespace: "appns"
  annotations:
    traefik.ingress.kubernetes.io/router.tls: "true"
  labels:
    app: appname      
spec:
  ingressClassName: traefik
  rules:  
  - host: someappurl.example-com
    http:
      paths:
      - path: "/"
        pathType: Prefix
        backend:
          service:
            name: appname
            port:
              number: 80

This is published on an internal IP, with a valid certificate. When I am trying to reach the ingress from within the vnet I get the http -> https redirect, but after that it stops. Wget looks like this:

root@somepod-66669dcfff-jg6vm:/app# wget someappurl.example-com
--2022-11-07 14:10:00--  http://someappurl.example-com/
Resolving someappurl.example-com (someappurl.example-com)... 10.0.0.150
Connecting to someappurl.example-com (someappurl.example-com)|10.0.0.150|:80... connected.
HTTP request sent, awaiting response... 301 Moved Permanently

Any suggestions on what to look for here? In the Traefik dashboard it looks alright with the router, service, and middleware all showing with a green checkmark. If I proxy directly to the service it works (I.e bypassing Traefik)

The mistake here was simple:

Thought namespace exclusion in a network policy was enough, but needed to allow cluster CIDR aswell
