traefik 404 page not found

[Amiyumi23]

I tried to run traefik and it didn't work.
I installed Kubernetes from here quick start.. https://k3s.io/
According to this guide and watching the video.
https://technotim.live/posts/kube-traefik-cert-manager-le/

I reached the point in the guide ""Visit https://traefik.local.example.com""
But I'm logging in using a local IP address http://192.168.178.225/ - 404 page not found

type: LoadBalancer
I don't use it yet and I don't have it installed.
I edit file values.yaml

service:
  enabled: true
  type: NodePort
  ports:
    web:
      port: 80
      nodePort: 30080  
    websecure:
      port: 443
      nodePort: 30443 

helm install --namespace=traefik traefik traefik/traefik --values=values.yaml

kubectl apply -f default-headress.yml
kubectl apply -f ingress.yml
kubectl apply -f middleware.yml

Log Pod:

kubectl logs -n traefik traefik-f44b9dcc6-cbmkn

what am i doing wrong? i even changed the port in the file values.yaml to 443 instead of this:
advertisedPort: 4443

in file default-headers.yaml
I used it like this for traefik version 3

apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
...
...

I am also having the same issue. Have yet to dig deeper.

Edit:

After running kubectl logs -n traefik deployment/traefik

I saw that I had issues with auth middleware

2025-03-27T19:55:04Z ERR Error while reading basic auth middleware error="secret 'traefik/traefik-dashboard-auth' not found" middlewareName=traefik-traefik-dashboard-basicauth providerName=kubernetescrd
2025-03-27T19:55:05Z ERR Error while reading basic auth middleware error="secret 'traefik/traefik-dashboard-auth' not found" middlewareName=traefik-traefik-dashboard-basicauth providerName=kubernetescrd

Correcting this fixed the issue.
