Azure数据同步错误

Question

我使用Windows Azure数据同步代理将内部数据库同步到SQL Azure DB，

我在同步过程开始后遇到以下错误。

"Blob transfer failedInner exception: One or more errors occurred.Inner exception: 
    One or more errors occurred.

    Inner exception: The Data Transfer Service has encountered a fatal error when performing the data upload.
    Inner exception: The remote server returned an error: (403) Forbidden.
    Inner exception: The remote server returned an error: (403) Forbidden." 

任何人都对这个错误有所了解。
