AngularJS app运行在Chrome上提供ERR_CONNECTION_REFUSED

I'm creating Angular application using cg-angular generator that have phalcon as back-end. I use configureProxies to connect back-end and front-end. My Gruntfile.js is

Gruntfile.js

/*jslint node: true */
'use strict';

var pkg = require('./package.json');

var createFolderGlobs = function(fileTypePatterns) {
  fileTypePatterns = Array.isArray(fileTypePatterns) ? fileTypePatterns : [fileTypePatterns];
var ignore = ['node_modules','bower_components','dist','temp'];
var fs = require('fs');
return fs.readdirSync(process.cwd())
      .map(function(file){
        if (ignore.indexOf(file) !== -1 ||
            file.indexOf('.') === 0 ||
            !fs.lstatSync(file).isDirectory()) {
          return null;
        } else {
          return fileTypePatterns.map(function(pattern) {
            return file + '/**/' + pattern;
          });
        }
      })
      .filter(function(patterns){
        return patterns;
      })
      .concat(fileTypePatterns);
};

module.exports = function (grunt) {
require('load-grunt-tasks')(grunt);
grunt.initConfig({

when I run grunt server it say

Running "configureProxies:server" (configureProxies) task Proxy created for: / to 0.0.0.0:80

Running "connect:livereload" (connect) task Started connect web server on http://localhost:8000

When I rout to my php back-end in browser it shows my encoded json data. in my angular app have get request ($http.get('url').success(function(data){log.console(data)});) but I rout to localhost:9001 it's gives error

ERR_CONNECTION_REFUSED

something wrong with my gruntfile?. how can I fix this?.

    After some researches and few discussion I can resolve the problem. problem is in the grunt file. Even if I have set connect option as port 9001 it runs on Port 8000 because of that I get the chrome error So I change the grunt file connect part to like this.

    connect: {
      proxies: [{
                context: ['/api'],
                host: '0.0.0.0',
                port: 80,
                https: false,
                changeOrigin: true
            }],
    //In here I remove the main:{}
        options: {
          port: 9001,
          hostname: '0.0.0.0',
          directory: '.', 
          livereload: 35730
      },
      livereload: {
                options: {
                    middleware: function(connect, options) {
                        if (!Array.isArray(options.base)) {
                            options.base = [options.base];
                        }
                        // Setup the proxy
                        var middlewares = [require('grunt-connect-proxy/lib/utils').proxyRequest];
                        // Serve static files.
                        options.base.forEach(function(base) {
                            middlewares.push(connect.static(base));
                        });
                        // Make directory browse-able.
                        var directory = options.directory || options.base[options.base.length - 1];
                        middlewares.push(connect.directory(directory));
                        return middlewares;
                    }
                }
            }
    },
    

    also I change the load sequence of sever Task like this. and put the more important task in the start like "configureProxies:server" and "connect:livereload"

    grunt.registerTask('serve', ['configureProxies:server', 'connect:livereload','dom_munger:read','jshint', 'watch']);
    

    and those changes work for me and work nicely in my browser.
