When I change something on the page I got following error from update request:
XMLHttpRequest cannot load http://localhost:3000/assets/bundles/108f5136d63f38ea9442.hot-update.json. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8000' is therefore not allowed access.Fix was to add Access control header to hot reload server responses.
