I'm trying to configure the plugin to work with my company porxy, the only ports opens are http and https, i have setup the environment correctly to use the porxy and other plugins are fine connecting. JENKINS also is able to connect for updates and plugins.

Also i have setup tomcat to start JVM with the proxy configuration. None of this works for this plugin.

When i try to setup the plugin and validate settings i got this error.
