  • First thing, I'd try updating your local Angular CLI version through the package.json directly, delete your node_modules folder, and npm install. If the CLI is running at 1.7.4, it might just not be able to make the connection that it's attempting. – sadq3377 Oct 01 '18 at 20:02
  • I think it is a connection thing, do you use proxy? or something else that could cause networking errors? – Gaspar Oct 01 '18 at 20:11

This is usually an npm issue with a proxy, not really a CLI issue.

Take a look at Using npm behind corporate proxy .pac

Basically, you need to make sure you have configured npm to work through your proxy, then ng cli should have not issues connecting.

npm config set proxy "http://domain\username:password@servername:port/"

Please note this saves you password on the config file, so after you are done you may want to remove the saved password like so"

npm config delete proxy
