You set $wsr as an instance of LWP::UserAgent and set the proxy server on this instance but you don't use it. You then set $useragent as another instance of LWP::UserAgent, don't set the proxy server and use this latter instance to submit your request.

Does it work if you set the proxy server on the $useragent instance?
