When passing a region to a new interface the the end URL is created with the wrong structure;
<region>.<service>.amazonaws.cominstead of<service>.<region>.amazon.comas per the given pattern from Amazon (see http://docs.amazonwebservices.com/general/latest/gr/rande.html#elb_region).The created URL seems to be valid for ec2 endpoints (both patterns work) but not for 'elasticloadbalancing'. Have not check with other services.
