XMLHttpRequest cannot load

Hi,

having troubles to get respond from mapquest api from my internal server :(

My code:

url = "http://open.mapquestapi.com/directions/v2/optimizedroute?key={{api_keys.mapquest}}&routeType=shortest";
            $.getJSON(url, {
                locations: locations
            })
            
            .done(function(data) {
                console.log(data);
            });

But I get always in chrome:
XMLHttpRequest cannot load http://open.mapquestapi.com/directions/v2/optimizedroute?key=...... No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://myserverinlocalnetwork' is therefore not allowed access.
