Proposed fix: [MinIO / S3] 400 AuthorizationHeaderMalformed 'The authorization header is malformed; the region is wrong; expecting 'us-east-1'.' — client signs for a different region than the server/b
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Set the client region to the one in the error (region_name / AWS_REGION / --region), or configure the MinIO site region to match your clients.
Option: Align the signing region [evidence: official_recommended_action]
Applies when: See record scope.
Steps:
1. Python: boto3.client('s3', endpoint_url=URL, region_name='us-east-1')
2. CLI: aws --region us-east-1 --endpoint-url URL s3 ls
Expected: Command proceeds without the error.
