I am trying to create a template, to test that our proxy is working - rather than relying on our users to complain when its running slowly. It would appear though that APM is not authenticating with the proxy, when asked for HTTP auth - I have set some credentials that have rights to access the internet. APM simply returns the error: "Unexpected error occurred. HTTP 407. Proxy authentication required. The remote server returned an error: (407) Proxy Authentication Required.".
In addition to this, the variables ${IP} and ${PORT} do not work in the Proxy field, which somewhat defies the point of creating a proxy template!
