AWS Elastic Transcoder Endpoint无法解析

Question

我正在开发一个项目，该项目需要对视频进行转码，并通过使用AWS Elastic Transcoder提取缩略图。我已经尽可能地遵循api并且在我看来正确的代码。但是，我仍然会收到NameResolutionFailure抛出的错误和一个内部异常，说The remote name could not be resolved: 'elastictranscoder.us-west-2.amazonaws.com'我的代码是：

        var transcoder = 
                      new AmazonElasticTranscoderClient(Constants.AmazonS3AccessKey, 
                                Constants.AmazonS3SecretKey, RegionEndpoint.USWest2);
        var ji = new JobInput
        {
            AspectRatio = "auto",
            Container = "mov",
            FrameRate = "auto",
            Interlaced = "auto",
            Resolution = "auto",
            Key = filename
        };

        var output = new CreateJobOutput
        {
            ThumbnailPattern = filename + "_{count}",
            Rotate = "auto",
            PresetId = "1351620000001-000010",
            Key = filename + "_enc.mp4"
        };

        var createJob = new CreateJobRequest
        {
            Input = ji,
            Output = output,
            PipelineId = "1413517673900-39qstm"
        };

        transcoder.CreateJob(createJob);

我在俄勒冈州配置了我的s3存储桶，并添加了使文件公开的策略。

显然我的虚拟机没有连接到互联网，这就是nameresolutionfailure被抛出的原因。一切都很好。
