将SSL证书密钥传递给Amazon S3客户端对象C＃

Question

无法对启用了SSL的Amazon S3端点进行REST API调用。得到错误“根据验证过程，远程证书无效。”

我试图将证书密钥添加到X509store并使用AmazonS3Client调用Amazon S3

using (var store = new X509Store(StoreName.Root, StoreLocation.CurrentUser))
            {
                store.Open(OpenFlags.ReadWrite);
                cert = new X509Certificate2(Convert.FromBase64String(CERT_KEY)); //Hard coded the cert base 64 key
                store.Add(cert);

            }


using (_s3Client = new AmazonS3Client("accessKey", "secretKey", _config))
                {
                    ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true;
                    string serviceUrl = _s3Client.Config.DetermineServiceURL();

                    PutObjectRequest putObjectRequest = new PutObjectRequest();
                    putObjectRequest.BucketName = "test-https";
                    putObjectRequest.Key = filename;

                    using (Stream stream = new MemoryStream(Encoding.UTF8.GetBytes("This is a Test File")))
                    {
                        putObjectRequest.InputStream = stream;
                        response = _s3Client.PutObjectAsync(putObjectRequest).Result;
                    }

我在PutObjectAsync方法调用上收到SSL验证错误。任何帮助将不胜感激
