Amazon S3 - 远程服务器返回错误：（407）代理身份验证

Question

我有以下代码在s3中上传文件。

AmazonS3 s3Client = AWSClientFactory.CreateAmazonS3Client("AWSAccessKey", "AWSSecretKey");

String strS3KEY = "JSON_FILE_NAME";
PutObjectRequest request = new PutObjectRequest();
request.WithBucketName("AWS_BUCKET");
request.WithKey(strS3KEY);
request.WithContentBody("Test");
request.CannedACL = S3CannedACL.PublicRead;
s3Client.PutObject(request);

这可以在本地系统中找到。当我从部署服务器中的 s3Client.PutObject（request）; 行运行应用程序时，它会出现以下错误 -

远程服务器返回错误：（407）需要代理验证。
