Can't open Nuxt.js starter template at Cloud9

Can't open Nuxt.js starter template in the browser (I see Cloud9 page: No application seems to be running here! Cloud9 can't get you to your requested workspace...).

Сhosen template is Blank.

Node.JS installed by NVM and I choose version v6.10.2 (Latest LTS: Boron)

Little editing package.json of nuxt.js starter template, cause default port is 3000, but in c9 available only 8080, 8081, 8082 :

  "config": {
    "nuxt": {
      "port": "8080"
       }
  },

Then I run app (npm run dev) and see everything is ok in console:

mytemplateapp@1.0.0 dev /home/ubuntu/workspace/mytemplateapp
> nuxt

Open http://127.0.0.1:8080

I've already tried all three available ports.

Well, I am stuck. I would appreciate any advice
