Calls to mock hang/ never return?

I am testing my code in my test class as follows: ` @BeforeMethod(groups="dao") public void beforeMethod() { api = new S3Mock.Builder().withPort(8001).withInMemoryBackend().build(); api.start(); s3Dao = new S3DaoImpl(AppConstants.S3_ENDPOINT_LOCAL); base64ImageDto = new Base64ImageDto("data:image/png;base64,324987sdfjkasdf", "test_dao_file.png"); preSignedFileName = "test-nhs-logo-3.png"; }

@AfterMethod(groups="dao")
public void afterMethod(){
    api.shutdown();
}

/*
 * Test the upload image functionality of the service
 */
@Test(groups="dao")
public void testS3DaoUploadBase64Image() {
    InitActions.testCaseDescription.set("Testing s3Dao upload base64image function.");

    String key = s3Dao.uploadBase64Image("TESTTEST", base64ImageDto);

    Assert.assertNotNull(key);
}`

and the Dao implementation is here: ` public String uploadBase64Image(String nhsId, Base64ImageDto base64ImageDto) { InputStream stream = new ByteArrayInputStream(base64ImageDto.getImageBytes()); AWSCredentials credentials = new BasicAWSCredentials(userId, secretId);

    try {
        LOGGER.info("Uploading file " + base64ImageDto.getFileName() + " to UKCloud S3");
        AmazonS3 s3Client;

        if(AppConstants.S3_ENDPOINT_LOCAL.equalsIgnoreCase(endPoint)) {
            AwsClientBuilder.EndpointConfiguration endpoint = new AwsClientBuilder.EndpointConfiguration("http://localhost:8001", "us-west-2");
            s3Client = AmazonS3ClientBuilder
                    .standard()
                    .withPathStyleAccessEnabled(true)
                    .withEndpointConfiguration(endpoint)
                    .withCredentials(new AWSStaticCredentialsProvider(new AnonymousAWSCredentials()))
                    .build();

        } else {
            s3Client = AmazonS3ClientBuilder.standard()
                    .withCredentials( new AWSStaticCredentialsProvider(credentials))
                    .withEndpointConfiguration(new AwsClientBuilder.EndpointConfiguration(endPoint, signingRegion))
                    .withPathStyleAccessEnabled(true)
                    .build();
        }

        ObjectMetadata metadata = new ObjectMetadata();
        metadata.setContentLength(base64ImageDto.getImageBytes().length);
        metadata.setContentType("image/"+base64ImageDto.getFileType());

        // Create Object key for upload
        Instant instant = Instant.now().truncatedTo( ChronoUnit.SECONDS );
        String dateTime = instant.toString();  // Generate a `String` object in standard ISO 8601 format.

        // Key format = <NHS#>_<TEMPLATE#>_<DATETIME>.<FILE TYPE>
        String key = nhsId + "_" + base64ImageDto.getFileName().substring(0, base64ImageDto.getFileName().indexOf("."))+ "_" + dateTime + "." + base64ImageDto.getFileType();

        PutObjectRequest request = new PutObjectRequest(bucketName, key, stream, metadata);

        if(AppConstants.S3_ENDPOINT_LOCAL.equalsIgnoreCase(endPoint)) {
            s3Client.createBucket("zeus-webapp-drop-test");
        }

        s3Client.putObject(request);
        return key;
        // TODO: return the URL location for & store in documentReference object
    } catch(AmazonServiceException e) {
        // The call was transmitted successfully, but Amazon S3 couldn't process
        // it, so it returned an error response.
        LOGGER.info("Error uploading file " + base64ImageDto.getFileName() + " to  S3");
        LOGGER.error(e);
        return "error";
    }
    catch(SdkClientException e) {
        // Amazon S3 couldn't be contacted for a response, or the client
        // couldn't parse the response from Amazon S3.
        LOGGER.info("Error uploading file " + base64ImageDto.getFileName() + " to  S3");
        LOGGER.error(e);
        return "error";
    }
}`

The method hangs when it gets to s3Client.createBucket("zeus-webapp-drop-test") and I am not sure how to troubleshoot this as it is a call to the client itself... Has this happened to anyone?
