I have installed Traefik on Kubernetes and followed allong the official tutorial. I have a cluster of 4 machines for Kubernetes.

When I run kubectl --namespace=kube-system get pods I see traefik-ingress-controller-678226159-eqseo, so all fine.

Then I executed:

kubectl apply -f https://raw.githubusercontent.com/containous/traefik/master/examples/k8s/ui.yaml

and then ran:

echo "$(my master node ip) traefik-ui.minikube" | sudo tee -a /etc/hosts

which resulted in: http://192.168.178.31 traefik-ui.minikube in /etc/hosts

I further edited kubectl -n kube-system edit service traefik-web-ui service and changed the type to NodePort.

When I finally run $ curl http://192.168.178.31:31107 I get:

curl: (7) Failed to connect to 192.168.178.31 port 31107: Connection refused

Does anyone know, why I am getting the Connection refused?

EDIT 1:

Log from kubectl logs -f traefik-ingress-controller-68994b879-5z2xr -n kube-system:
