      Thank you for your help.
      My WordPress site runs on GCP for free.
      And I’m using Cloudflare from CDN.
      yesterday,
      After executing kusanagi restart, “Error 521”
      “Web server is down” is displayed and the site can no longer be accessed.
      That situation is still going on.
      I don’t know how to get it back.
      Please help someone.

      皆様、申し訳ありません。
      英文で投稿しなければならないのかと思ってしまいました。

      日本語でも投稿させて頂きます。
      件名:「kusanagi restart を実行したら Error 521 と表示される」

      お世話になります。
      当方のWordPressサイトはCDNのCloudflareを使用していますが、
      昨日、
      kusanagi restartを実行した後、ブラウザ上で「Error 521」
      「Webサーバーがダウンしています」と表示され、サイトにアクセスできなくなってしまいました。
      その状況は現在も続いています。
      元の状態に戻す方法が分からず、困っております。
      当方kusanagi及びサーバー初心者のため、下手に追加の対処をしようとすると致命的な結果になりかねないかもしれないと思っています。

      どなたかお詳しい方、ご助言頂けないでしょうか?
      どうぞよろしくお願い申し上げます。

      nginxの起動状況など分からないので何とも言えませんが、521はcloudflareのエラーのようです。
      下記などはチェックされてますでしょうか。

      WordPressとCloudflareの521エラーの処理方法について
