Problem description
PostObject requests signed with the Amazon S3-compatible Signature Version 2 (V2) fail because V2 is unavailable for Amazon S3-compatible operations.
Causes
The Amazon S3-compatible API does not support Signature Version 2 (V2) for PostObject requests — V2 is unavailable. Only Signature Version 4 (V4) is accepted.
Examples
A PostObject request is signed using the Amazon S3-compatible V2 signature. OSS rejects the request because V2 is unavailable for this operation.
Solutions
Re-sign the PostObject request using Signature Version 4 (V4).
For implementation details, see PostObject.
