Preview Angular App Not Working

I can’t preview my angular 8 app (node 10) in Cloud9.

My start command is - “start”: “ng serve --host $IP --port $PORT --disable-host-check”
And I’ve tried setting my security policy to specifically allow port 8080.

All the other threads indicate this is all I should have to do. Anyone know any other reason why Preview wouldn’t work?


Could you make sure that you’re starting your Angular app on host, not
