我发布了 Azure Web Role 项目，并启用了 CPU 分析器。当我请求分析报告时，我得到了
19:04:43 - Connecting to the Profiling agent on the VM instance
19:04:44 - The Profiling agent is preparing to process the request
19:04:45 - Preparing the Profiling logs on the VM instance
19:05:00 - Uploading the logs from the VM instance to the Microsoft Azure storage account.
19:05:01 - Profiling log request failed. Details: Profiling agent failed to upload log snapshot to Microsoft Azure storage account
存储帐户似乎没有问题（我试了两个）。如何摆脱这个错误？
