Common Issues

Problem	Cause	Solution
Access denied	Wrong AccessKey permissions	Check RAM permissions for OSS bucket access
Signature mismatch	Wrong region selected	Re-select the exact region used by the bucket
Bucket not found	Bucket name or region mismatch	Verify both values in the OSS console
Connection works but listing fails	Credentials lack list permissions	Ensure the key can read bucket metadata and list objects
