问VodUploadClient视频服务器端上传，Upload函数一直卡死，没有返回？

VodUploadClient client = new VodUploadClient("AKIDKzzEwHcP0zYFpvtuszq4ee", "unamPChPBNn69jj");

VodUploadRequest request = new VodUploadRequest();

request.MediaFilePath = Server.MapPath("~/data/1234.mp4");

WriteTxt("MediaFilePath:" + request.MediaFilePath);

// request.MediaFilePath = "~/data/1234.mp4";

try

{

VodUploadResponse response = client.Upload("ap-shanghai", request);

WriteTxt("ResponseMediaUrl:" + response.MediaUrl);

WriteTxt("ResponseFileId:" + response.FileId);

WriteTxt("ResponseRequestId:" + response.RequestId);

// 打印媒体 FileId

Console.WriteLine(response.FileId);

}

catch (Exception e)

{

WriteTxt("Catch:" + e.Message.ToString());

// 业务方进行异常处理

Console.WriteLine(e);

}

文件路径和密钥ID，区域设置这些都没有错，就是调用Upload

一直卡死，没有返回，在线等知道的朋友帮下忙，这些东西真的不熟悉
