kubernetes - kubespray scale.yml を使用したスケーリングが「Failed to connect host via ssh」で失敗する

Question

Kubespray cluster.yml - 以下のコマンドで正常に動作します。

使用したコマンド:

ansible-playbook -b cluster.yml -i inventory/sample/hosts.ini -e kube_version=v1.13.2 -vvv

ただし、スケーリングは次のメッセージで失敗します..つまり、kubelet.conf ファイルが作成されるのを待っています。

NO MORE HOSTS LEFT **********************************************************************************************************************************
    to retry, use: --limit @/root/kubespray_stg/scale.retry

SSH 接続は良好です。

タイムアウトを増やしてみました

/root/kubespry/roles/kubernetes/kubeadm/tasks/main.yml ファイルですが、うまくいきません。
