Angular2 Demo don't work. Error 2002

I have download Angular2 example from JS-SDK replace APP-ID and APP-KEY in main.ts. But it don’t work with code 2002.

What version of the backend did you use? 3.x or 4.0?

I use https://api.backendless.com

Right, both 3.x and 4.0 are accessible through that address. Login to console and check the version number right next to the Backendless logo.

npm installed v 3.1.25

I am talking about this: http://take.ms/bWM8j

v 4

with v3 it work correctly, but with v4 …

Extract files from the ZIP. Run “npm install” from the root directory of the project. The project is ready to run and will show you how to do some basic Backendless APIs.
