Graphite should inherit whatever proxy settings there are in Control Panel > Internet Options. That is to say - if Mist running in Internet Explorer can connect to our backend, then so should Graphite.
Could you please run Fiddler
and then start Graphite? Do any failed requests to *.icenium.com or *.telerik.com appear in Fiddler's log? If so, can you please export the logs and send them to support [AT] icenium.com?
