I can't connect table, but connect blob is ok.

Here is my code:

storageAccount = CloudStorageAccount.Parse(CloudConfigurationManager.GetSetting("tableStorage"));

audioBlob = storageAccount.CreateCloudBlobClient().GetContainerReference("mycontainer");
bool y = audioBlob.Exists();

CloudTableClient tableClient = storageAccount.CreateCloudTableClient();
submitInfoTable = tableClient.GetTableReference("people");
bool x = submitInfoTable.Exists();

I debug it, y is "true".
But when it run to "bool x = submitInfoTable.Exists();", I am waiting long time and it is no response.

Anyone konw how to solve it? Please help me!
