What is the official way to setup online updates if servers are behind proxy ?
No proxy configuration in GUI, when defining the proxy via yast2 it accepts it as I can wget from internet sites, but online update configuration still fails with "An error occurred while communicating with the server. Status code: 500 (The call failed on the server; see server log for details)".

Our proxy server is x.x.x.x:80 for all protocols .
