我正在尝试使用 将大图像文件上传到 cloudinary IFormFile，但出现以下错误：

System.Threading.Tasks.TaskCanceledException: The operation was canceled.
 ---> System.Net.Http.HttpRequestException: Error while copying content to a stream.
 ---> System.IO.IOException: Unable to read data from the transport connection: The I/O operation has been aborted because of either a thread exit or an application request..
 ---> System.Net.Sockets.SocketException (995): The I/O operation has been aborted because of either a thread exit or an application request.
   --- End of inner exception stack trace ---

该代码使用文件流上传图像：

public VideoUploadResult UploadClip(IFormFile videoFile)
{
    var uploadResult = new CloudinaryDotNet.Actions.VideoUploadResult();
    if (videoFile.Length > 0)
    {
        // create a new file stream to upload the video to cloudinary
        using (var filestream = videoFile.OpenReadStream())
        {
        var uploadParams = new VideoUploadParams
        {
            File = new FileDescription(videoFile.FileName, filestream),
            Transformation = new Transformation().StartOffset("0").EndOffset("60").Crop("fill")

        };
        uploadResult = _cloudinary.Upload(uploadParams);

        }
    }

    // checks if error occurs when uploading video
    if (uploadResult.Error != null)
    {
        throw new Exception(uploadResult.Error.Message);
    }

    return new VideoUploadResult
    {
        PublicId = uploadResult.PublicId,
        Url = uploadResult.SecureUrl.AbsoluteUri
    };
}

videouploadresult只是一个简单的类，它在上传到 Cloudinary 时具有文件的和publicid属性url。有没有其他方法可以通过 API 上传大文件？还是代码有问题？

它适用于 30MB 以下的文件，我还允许我的 kestrel sevrer 能够上传高达 200MB 的文件，但我仍然遇到错误。我认为该错误源于尝试打开大文件的读取流，并且我已经阅读过使用IFormFile大文件不好的地方。但我还没有看到任何替代方案。
