What is the problem with gulp?

Question

gulp.js

Good evening, I ran into a problem, gulp crashes with an error after a few minutes of work

events.js:154
      throw er; // Unhandled 'error' event
      ^

Error: connection refused: localtunnel.me:33235 (check your firewall settings)
    at Socket.<anonymous> (D:\test\OLIOS_one_page\node_modules\localtunnel\lib\TunnelCluster.js:47:32)
    at emitOne (events.js:90:13)
    at Socket.emit (events.js:182:7)
    at emitErrorNT (net.js:1258:8)
    at _combinedTickCallback (node.js:383:13)
    at process._tickCallback (node.js:407:11)

I took the gulp config from this post https://habrahabr.ru/post/250569/
Can someone come across this ???

Answer 1

Yes, everything is extremely simple: localtunnel.me:33235 server conflict (clogged by many users - it's free), reload, or select a different port, here

var config = {
    server: {
        baseDir: "./build"
    },
    tunnel: true,
    host: 'localhost',
    port: 9000, // измените
    logPrefix: "Frontend_Devil"
};
