The setup I am using, is I have a Node.js, express server that is listening on port 1337 using the host 127.0.0.1.
I then have Webpack dev server running on port 3000 and it proxies all traffic from 3000 to 1337, the server. Webpack dev server runs as a default on host 127.0.0.1 and for security reasons, other computers internally cannot access any server from that host.
As a fix, I had to change the (default) host to 0.0.0.0 in order to then access the internal ip and port (http://192.168.100.54:3000).
