We're currently facing the same issue when trying to upgrade to 1.9.4-gke.1 
with no way forward to resolve this.
The cluster reports it's fine.

$ kubectl get cs
NAME                 STATUS    MESSAGE              ERROR
scheduler            Healthy   ok
controller-manager   Healthy   ok
etcd-0               Healthy   {"health": "true"}
etcd-1               Healthy   {"health": "true"}
