I get this error when I upload my site to my webserver:

http://desktop-gq7oerj:3000/sockjs-node/info?t=1489850537555 net::ERR_CONNECTION_REFUSED

my webpack config is:

 entry: [
    'webpack-dev-server/client?http://' + require("os").hostname() + ':3000/',
    'webpack/hot/only-dev-server',
    './src/index'
],

How can I fix it?

How can I fix it?

• javascript
• webpack
• webpack-dev-server

• Is your server listening on port 3000? – Matt Commented Apr 4, 2017 at 0:22
• Thanks for your reply. Is there a way I can find out? As the error is ing from my dev server, do I even need it running in production? – Bomber Commented May 16, 2017 at 15:08
• You say you're uploading it to your webserver? Webpack-dev-server is not for production use. What you should do is use webpack to build production code and upload those. You then setup a node/nginx server to serve the static files. – uLan Commented Aug 4, 2017 at 10:14

In my case,it worked this => Here's a link

in webpack.config i aggregated :

devServer: {
      socket: 'socket',
      ...
    },

Try this

entry: production
        ? './src/index'
        : [
            `webpack-dev-server/client?http://0.0.0.0:${SETTINGS.PORT}`,
            'webpack/hot/only-dev-server',
            './src/index',
        ],
