私はこの間数日間苦労しています。 Django + django-storageとHerokuでstaticfilesにS3を使うHeroku：S3/boto3 - エラー：AWS4-HMAC-SHA256を使用してください。
まずS3バケット4f2xivbz443を作成し、アクセスキー（アクセスキーIDとシークレットアクセスキー）を生成します。
django-storageshttps://django-storages.readthedocs.io/en/latest/がインストールされており、Amazon S3の追加と設定の手順に従っています。私が展開するとき
私はこのエラーを取得：
raise error_class(parsed_response, operation_name)
botocore.exceptions.ClientError: An error occurred (InvalidRequest) when calling the PutObject operation: The authorization mechanism you have provided is not supported. Please use AWS4-HMAC-SHA256.

EUフランクフルトの代わりにバケットをUSスタンダードに変更すると、エラーは発生しません。ファイルはバケツに正しく転送されます。ヨーロッパだけの問題のようだ。誰もこれを解決する方法を知っていますか？ – swaTuesiSe
