Access Control Allow Origin?

What is might be the problem here? Do I need to set some setting on the dev server for this to work?

Failed to load resource: the server responded with a status of 404 (Not Found)
10.0.1.27/:1 XMLHttpRequest cannot load http://10.0.1.27:9090/build/2590dcf104e749604e15.hot-update.json. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://10.0.1.27:8080' is therefore not allowed access. The response had HTTP status code 404.

Thanks @Dakuan, I ended up setting the headers when I start the server. Here’s the code:

var webpackDevServer = require('webpack-dev-server');
new webpackDevServer(webpack(webpackConfig), {
  publicPath: "http://localhost:8080/build",
  hot: true,
  headers: { "Access-Control-Allow-Origin": "*" }
}).listen(settings.ports.hotPort, 'localhost', function(err, result){
  if(err){
    console.PluginError(err);
  }
  console.log('Webpack hot load server listening on port ' + settings.ports.hotPort);
});

@hugotox in your webpack config, try adding this:

devServer: {
    headers: { "Access-Control-Allow-Origin": "*" }
  },
