title: Gulp livereload is doing nothing
body: <p>How do I setup gulp live-reload, it doesnt seem to be doing anything.</p>
  
  <p>this is part of my gulpfile:</p>
  
  <pre><code>var livereload = require('gulp-livereload'),
      lr = require('tiny-lr');
  
  gulp.task('css', function(){
           gulp.src(sassdir)
          .pipe(sass({style:'compressed'}))
          .pipe(prefix('last 4 version'))
          .pipe(gulp.dest(cssdir))
          .pipe(livereload(lr()));
  });
  </code></pre>
  
  <p>I've tried gulp connect and gulp live reload with and without tiny-lr.</p>
  
  <p>If it helps, I'm running an apache webserver on a vagrant VM (ubuntu) with host pc windows. VM has static IP of 192.168.33.10.</p>
