This issue is so infuriating that I'm going to take some time to write about it.

MOST IMPORTANT. Your local development server must be bound to IP address 0.0.0.0. Some do this by default, but many don't. You need to make sure that you run your local server with correct IP bindings. You may need to provide additional flags to your serve commands e.g.
polymer serve --hostname domain.local
,hugo serve --bind 0.0.0.0
. If you use a named domain likedomain.local
, it has to be defined in/etc/hosts
and pointing at 0.0.0.0. -
My Parallels setting is using Shared Network, nothing special there.

Open macOS Terminal and type
ifconfig
. Look for the value undervnic0
>inet
. It is typically10.211.55.2
.
