Can't see my server on an azure vm

Question

I have an Azure vm with Ubuntu 12 and I want to make an Angular2 server with angular-cli. When I run ng serve --port 80 I just can't see the page with a browser. When I check with CURL from the vm I can see the HTML properly but I get an error when I try to see it from the internet.

The strangest thing is that anything else I try works perfectly, I also have an old node server on the vm and when I run that I can see it normally from CURL and from the internet.

Answer 1

Okay so apparently I needed to specify host : sudo ng serve --host 0.0.0.0 --port 80 .
