ClientResponseException in OpenStack4J on IBM Bluemix Object Storage service

Question

I am following this guide to connect to IBM Object Storage for Bluemix with Java: https://developer.ibm.com/recipes/tutorials/connecting-to-ibm-object-storage-for-bluemix-with-java/

I have double checked the values with the credentials in the service but when I execute the authenticate() method I get following exception:

Caused by: ClientResponseException{message=Not Found, status=404, status-code=NOT_FOUND}
    at org.openstack4j.core.transport.HttpExceptionHandler.mapException(HttpExceptionHandler.java:38)

Anyway I can know what is wrong? (URL, userId, password, project, domain, ...)

Thanks
