I am trying to migrate web application I'm working on to Angular 5.2.
Followed the instructions on https://angular-update-guide.firebaseapp.com/ ,
I've been able to run the application in the development mode using 'ng serve -lr' as usually.
However, after application launches, multiple HTTP requests, which weren't triggering on Angular 4.4 are executing and eventually, webpack-dev-server disconnects.
My package.json on Angular 4.4, before update:

Seems like the problem was in webpack live reloading. Solved it by adding parameter to launch script, now it is
ng serve --public-host http://localhost:4200/ -lr
