Storj s3 hosted gatway, internal error using c#

I´m getting an internal error with not much details while I´m trying to upload a small PNG file using your hosted s3 gateway.

I´m using c# and the s3 official package.

AmazonS3Client s3Client = new AmazonS3Client(
              “<ACCESS_KEY_ID>“,
              “<SECRET_KEY>”,
              new AmazonS3Config { ServiceURL = "https://gateway.us1.storjshare.io" }
              );

Stream imageStream = assembly.GetManifestResourceStream(“<FILE_PATH>”);
imageStream.Position = 0;

await s3Client.PutObjectAsync(new Amazon.S3.Model.PutObjectRequest
                    {
                        BucketName = “<BUCKET_NAME>”,
                        Key = “<FILE_KEY>”,
                        ContentType = "image/png",
                        InputStream = imageStream,
                    });

It only fails when I run the code against storj gateway, aws and other s3 compatible apis are accepting the request.

Am I missing something?.
