Up until today, "foreman start" command bind both rails and webpack to
0.0.0.0. This has changed since  which was merged this morning.
Currently "foreman start" will bind to localhost by default. Should you
want to change that you can either:
- Run "BIND=0.0.0.0 foreman start"
- Create a ".env" file which is read by foreman (the other foreman )
and add to it "BIND=0.0.0.0".
By the way you can add other environment variables to .env
