SignatureDoesNotMatch | Wrong secret or clock skew. SigV4 is time-sensitive, so sync your client’s clock. |
InvalidAccessKeyId | The credential is not known to this gateway. Credentials are issued per gateway and do not work on another one. |
AccessDenied | The credential does not cover this bucket, or the bucket’s tape has not delegated writes to this gateway (delegation). |
NoSuchBucket | The bucket name does not resolve to a tape. Use the bucket’s lowercase label. |
| Connection or SSL errors | Wrong endpoint. Check the three values at the top of this page. |
