I'm getting 404 error.

[bayeslearner]

kubectl -n kube-system port-forward $(kubectl -n kube-system get pods --selector "app.kubernetes.io/name=traefik" --output=name) 9000:9000

takes me to inspect the routes and the needed IngressRoute is not created there.

[bayeslearner]

helm -n kube-system get values traefik -a

shows Ingressroute provider is enabled. Why didn't it work?

Hi @bayeslearner , thanks for opening this issue! Sorry for getting back to it this late.
Can you paste your curl output here as well?
I never really used the IngressRoute resource, but from a first glance I think it should work that way if you do curl -k https://whoami.192.168.8.118.nip.io (given that that's your correct IP) 🤔

[iwilltry42]

@bayeslearner , any update on this?

[iwilltry42]

I just gave this a try (just using 8443 instead of 443 on my machine as it's in use already):

$ curl -k https://whoami.192.168.1.97.nip.io:8443

I also see the Route in the Traefik dashboard:
