Problems starting nginx-ingress-controller with the cluster site.yaml playbook

[hakor]

Setting the parameters as required and run the playbook with
ansible-playbook site.yaml
runs successful within our OpenStack cluster. Master and nodes created etc. But the nginx-ingress-controller did not start.
0/1 is ready when listing all pods.

The task "name: k8s - Install nginx-ingress via helm" in the play nginx-ingress.yaml did not succed.
The specified version 0.25.1 was not existing anymore. Removing the argument of the verion in this task
ended up in a successful playbook output.

Checking the IP adresses with
kubectl get svc --all-namespaces
results for the corresponding pod with
kube-system nginx-ingress-controller LoadBalancer 10.8.10.37 80:30627/TCP,443:30288/TCP 52m
It looks as if the IP is not exposed.

How can I access the kubernetes dashboard to check if everything is running ok?
