Uploadcare: Having trouble using Java Library to copy files from Uploadcare storage to AWS S3 bucket

I'm very new to Uploadcare. I am trying to retrieve a file UUID from Uploadcare, then use that UUID to copy the image to my S3 storage bucket. I am using the Uploadcare API available on git-hub:here.

The code is super easy to implement. Here's what I have:

package javaapplication2;

import com.uploadcare.api.Client;
import com.uploadcare.data.CopyFileData;
public class UploadAPITest {

public static void main(String[] args) {

    Client client = new Client("mypublicKey", "myprivateKey");
    CopyFileData copyFile = client.copyFile("d5e97aca-f6d9-47ea-8c76-1fe36d093b2d", "messagePicUploadCenter");
    System.out.println("result: " + copyFile.result);
}

This code compiles with no problem. Yet when I run it, this is the error I see:

enterException in thread "main" 
com.uploadcare.exceptions.UploadcareNetworkException: Network failure!

Has anyone else had this issue, or have some advice for me? I would really appreciate it. I love this service, and I think the issue has more to do with the com.faster.jackson.databind library. Here's a picture of the libraries I'm using in this simple project: http://ift.tt/1ASHxHF
