Description
Type: Bug
Run angular app from inside container. Ports tab shows that port 4200 is forwarded automatically. However the browser hangs waiting for, "http://localhost:4200 " to display a webpage.
I've also tried to forward the port explicilty from devcontainer.json which doesn't resolve the problem. When I run the Angular app locally it loads immediately in the browser.
