サーバーが公開鍵認証のみを許可しているため、接続がブロックされました[PuTTY致命的エラー]

私がホストするEC2インスタンスを作成したところDjangoプロジェクトで、Windows 10(会社のPC)を使用しているため、PuTTY経由でインスタンスに接続しようとしています。

Amazon LinuxおよびUbuntu Server 18.04のディストリビューションで documentation 手順を実行しようとしましたが、常にPuTTYから次のエラーが発生します。

サーバーが公開鍵認証のみを許可しているため、接続がブロックされましたネットワーク管理者に連絡してください。

私がすでに試したこと:

  • セキュリティグループは世界中に公開されています(すべてのトラフィック)。
  • ユーザー名は正しいです。
  • キーが.pemから.ppkに変換されました
  • 変換されたキーは、SSH> Authで設定されました。
  • 私は制限なしでオープンネットワークにいます。
  • .pem元のファイルを使用するために、mobaxtermも(GUIおよびコマンドラインを介して)使用しようとしました-同じエラー。

別のSSHツールを試した後、EC2構成の詳細になる可能性があると思います...

私はプロジェクトをホストするためにこれにこだわっています。誰かが私を解決策に導くことができますか?

ありがとう!

エラーメッセージをグーグルで検索すると、最初の2つの関連ヒットはどちらも、問題はファイアウォールのSSHインスペクションが原因であると主張しています。


これは動作を説明します。サーバーが「OpenSSH」であると主張している(そして実際のサーバーはおそらくOpenSSHである)一方で、OpenSSHにはのようなエラーメッセージはありません。ネットワーク管理者」。エラーメッセージを挿入するのは、実際のOpenSSHサーバーに代わって動作する中間サーバー/デバイスである必要があります。
