You will need to use jsonp since the domain is different from your page (due to the port number). The xhr request is considered cross domain and is falling foul of the same origin policy.

See the Additional Notes section from the jquery getJson docs

Additional Notes: Due to browser security restrictions, most "Ajax" requests are subject to the same origin policy; the request can not successfully retrieve data from a different domain, subdomain, or protocol. Script and JSONP requests are not subject to the same origin policy restrictions.
