After deploying juju-gui, It isn't able to communicate with the Charm API for some reason.
When looking into the Chrome debugger I get errors like
XMLHttpRequest cannot load https://manage.jujucharms.com/api/2/charms?text=nod&autocomplete=true&limit=5. Origin https://ec2-xx-xxx-xx.compute-1.amazonaws.com is not allowed by Access-Control-Allow-Origin.
Any ideas?
