Have installed jenkins 2.409. Sauce on demand plugin1.212. Its set on localhost:8080 . On windows

Note:-configurations are correct, and the  endpoint is available when accessed via the proxy, as such this appears to be a Jenkins issue, as it is not applying the Jenkins Proxy config to the plugin 

However the Following error is given   :-
