You need to add a response header to your application, either in the image or if you're using apache or nginx at the webserver level to explicitly allow the fonts you want to load to be loaded.
Fonts and Javascript are restricted because they can do Nasty Things.
so in your image:
html requestContext response headerAt: 'Access-Control-Allow-Origin' put: 'http://example.com'
