curl コマンドを実行して、Docker コンテナー内の宛先 B にファイルをアップロードしようとしていますが、次のエラー メッセージが表示されます。ホスト サーバー上のコンテナー外でまったく同じコマンドを実行すると、正常に動作します。curl コマンドがホスト サーバー上で動作するため、ポート 443 が開いていることは明らかです。

実行中のコマンド。
curl -v 'https://dns.servername.com/service/rest/v1/components?repository=DevOps' -H 'accept: application/json' -H 'Content-Type: multipart/form-data' -H 'Authorization: Basic ZmFhZG1pbjotVXUzOEVKKlIhTGMjNXBe' -F 'raw.directory=Folder12345' -F '[email protected];type=application/x-zip-compressed' -F 'raw.asset1.filename=testfile.zip'
これはめったに機能しません。10～20 回試しても 1 回しか機能しません。
