grunt-browser-sync: Other device can not connect to computer's IP

(I couldn’t find another similar issue so I opened a new one.)

I’ve been using grunt-browser-sync for a while and so far it’s great!

But I have a problem when I try to use it with the watchtask and server options. Somehow I remember that the first time it worked, but now it stopped working.

On my computer I can go to both localhost:3002 and 192.168.0.108:3002 and on both browser-sync works perfectly (refresh, injection).

But when I try to visit 192.168.0.108:3002 on my phone (on the same wifi network) it keeps saying it can’t connect to the IP (“Google Chrome could not connect to 192.168.0.108:3002.”) and it displays the standard search bar.

Here’s the Grunt file I use (I only included the watch and browsersync tasks here):

module.exports = function(grunt) {

    grunt.initConfig({

        watch: {
            sass: {
                files: [
                    'sass/*.sass',
                    'sass/*.scss'
                ],
                tasks: ['sass:dist','autoprefixer']
            },

            style: {
                files: [
                    'sass/*.sass',
                    'sass/*.scss'
                ],
                tasks: ['sass:style']
            },

            js: {
                files: ['jsraw/**/*.js'],
                tasks: ['uglify']
            },

            content: {
                files: [
                    '*.htm',
                    '*.html',
                    '_layouts/*.htm',
                    '_posts/*.htm',
                    '_posts/*.md',
                    '_includes/*.htm',
                    'css/*.css',
                    'js/**/*.js'
                ],
                tasks: ['jekyll']
            }
        },

        browserSync: {
            files: {
                src: ['dist/css/*.css', 'dist/**/*.html','dist/js/*.js']
            },
            options: {
                browser: 'google chrome',
                watchTask: true,
                debugInfo: true,
                server: {
                    baseDir: 'dist/',
                    index: 'index.html'
                }
            }
        }

    });

    grunt.loadNpmTasks('grunt-contrib-watch');
    grunt.loadNpmTasks('grunt-browser-sync');

    grunt.registerTask('build', ['sass:dist','uglify','jekyll']);
    grunt.registerTask('default', ['build','browserSync','watch']);
    grunt.registerTask('style', ['build','browserSync','watch:style']);

I’m not sure what’s going wrong here… any tips for troubleshooting this? I’m on Linux (Ubuntu 14.04) 64bit, node v0.11.14-pre, grunt-cli v0.1.13, grunt v0.4.5, browser-sync v0.9.1.

Many thanks!
