Can't upload to Azure Media Services - File No

问题:

When I run the website locally, the video will upload to azure and I get a publish url. No problem. However, when I publish the website and then try to upload from there, I get this error:

I think you should use this to upload file by uploading the stream

public void UploadFileToAzure(Stream stream, string fileName, string contentType, 
    EContextType contextType) {
    if (stream == null)
        throw new ArgumentNullException("stream");

    if (fileName == null)
        throw new ArgumentNullException("fileName");

    CloudBlobContainer blobContainer = null;

    switch (contextType)
    {
        case EContextType.CloudStorage:
            blobContainer = AzureBlobUtil.InitializeBlob(Settings.AzureBlobStorageFileStorage, Settings.GetAzureDataConnectionString);
            break;
        default:
            blobContainer = AzureBlobUtil.InitializeBlob(Settings.AzureBlobStorageDocument, Settings.GetAzureDataConnectionString);
            break;
    }

    var blob = blobContainer.GetBlockBlobReference(fileName);
    blob.UploadFromStream(stream);

    blob.Metadata["FileName"] = fileName;
    blob.Metadata["IsArchived"] = false.ToString();
    blob.SetMetadata();
    // Set the properties
    blob.Properties.ContentType = contentType;

    blob.SetProperties();
}
