Task execution stuck on "start selenium standalone server"

tl;dr gulp task is stuck on "start selenium standalone server" step, I'm asking for help. I blame the corporate proxy settings but am not sure about anything.

I use pretty much the code from the README example in my gulpfile:

// gulpfile.js
var gulp = require('gulp')
  , webdriver = require('gulp-webdriver');

gulp.task('test', function() {
  return gulp.src('*/*.spec.js', { read: false })
             .pipe(webdriver({
                  desiredCapabilities: { browserName: 'chrome' },
                  proxy: {
                      httpProxy: // my companies proxy here
                      sslProxy:   // same here
                  }
             });
});

As dependencies i have installed

// package.json, devDependencies section
"gulp": "^3.9.0",
"gulp-webdriver": "^0.1.1",
"mocha": "^2.2.5",
"webdriverio": "^3.1.0"

When I run gulp test, it gets stuck on the start selenium standalone server step:

[08:57:00] {{ my workspace here }}\gulpfile.js
[08:57:00] Starting 'test'...
[08:57:00] run webdriverio with following capabilities: {"desiredCapabilities":{"browserName":"chrome"},"proxy":{"httpPr
oxy":"{{ my companies proxy here }}","sslProxy":"{{ and here }}"}}
[08:57:00] checking if selenium is running
[08:57:01] selenium is not running
[08:57:01] installing driver if needed
[08:57:02] driver installed
[08:57:02] start selenium standalone server

I'm on a windows (:disappointed:) 8.1. 64bit machine with node -v v0.12.7 and npm -v 2.11.3.

I'd expect the task to start the selenium server and run my specs. What am I missing?
