the kube-apiserver isn't running

/var/log/kube-apiserver.log has the following:

Flag --address has been deprecated, see --insecure-bind-address instead.

Where are these values stored / configured?

I mean yes the originate from my kops config, which I've now modified. But I'm not able to get these changes reflected:

kops rolling-update cluster
Using cluster from kubectl context: uuuuuuuuuuuuuuuuuuuuuu
Unable to reach the kubernetes API.
Use --cloudonly to do a rolling-update without confirming progress with the k8s API


error listing nodes in cluster: Get https://api.uuuuuuuuuu/api/v1/nodes: dial tcp eeeeeeeeeeeeeee:443: connect: connection refused
