Soap4r : the requested address is not valid in the its context

I was wondering if somebody has seen this error before?

I'm trying to connect to a service, I just generated this soap client from wsdl2ruby. Everything went fine. So I have no idea why this error is happening. This is a fresh install of ruby 1.8.7 on Windows, but I tested this on another Windows machine with Ruby 1.8.6 and on a Debian server with REE 1.8.7 - same error. My gut feeling is that it has to do with the httpclient lib - but I can't find anything on google - regarding this err, other than some references to Pythong and tcl - which seem to be unrelated. Also I'm trying to connect to wsdl service that is on httpS - but I didn't have this problem before and there were no changes on the server.

Does anyone have any insight?

OK nevermind people. For anyone else looking into this cryptic message if you are using wsdl2ruby - make sure that you define your endpoint_url in the WhateverServiceClient.rb file generated by the wsdl3ruby.
