title: Unable to connect to selenium from webdriverio. Got blocked by firewall
body: <p>I have nodejs webriverio setup to run my cucumber test-cases. I am using standalone selinium server. The selinium server is started using chrome driver. I can see response when i take <a href="http://localhost:4444/wd/hub/session" rel="nofollow noreferrer">http://localhost:4444/wd/hub/session</a> in browser. </p>
  
  <p>When running test through webdriverio, the selinium server url <a href="http://localhost:4444/wd/hub/session" rel="nofollow noreferrer">http://localhost:4444/wd/hub/session</a> is getting blocked by firewall. I dont know why it is getting blocked because, accessing that url through browser is working fine without issues.</p>
  
  <p>I am using </p>
  
  <p>selenium-server-standalone-2.42.2.jar</p>
  
  <p>Webdriverio 4.4.0</p>
  
  <p>How does wdio connect to selinium? Not through http?? I am behind corporate proxy and firewall from z-scaler. </p>
