The warped request timed out when waiting for a response for the request [GET /login.jsf].

The 2 other request/-s were noticed by Warp for the given activity: [GET /authenticated.jsf] and [GET /header.png].

There were no requests done for observer: [request().uri().contains("/rest")].

If Warp enriched a wrong request, use observe(...) method to select appropriate request which should be enriched instead.
Otherwise check the server-side log and enable Arquillian debugging mode on both, test and server VM by passing -Darquillian.debug=true.
