I've a very strange error in my kubernetes configuration. When I'm trying to connect to KubeDNS (I'm using minikube) I have the following error:

{
  "kind": "Status",
  "apiVersion": "v1",
  "metadata": {

  },
  "status": "Failure",
  "message": "services \"kube-dns:dns\" is forbidden: User \"system:anonymous\" cannot get resource \"services/proxy\" in API group \"\" in the namespace \"kube-system\"",
  "reason": "Forbidden",
  "details": {
    "name": "kube-dns:dns",
    "kind": "services"
  },
  "code": 403
}

I read something about RCAD but I can't find anything that explaine clearly what must I do. Can anyone help me?
