Problem description
The authentication mode that is compatible with Amazon S3 and uses the V4 signature is not enabled for Object Storage Service (OSS).
Causes

Examples
An Amazon S3 SDK is used to initiate a request for which authentication is performed based on the V4 signature.
Solutions
Use an authentication mode supported by OSS rather than Amazon S3 in the request. For more information, see Overview.
