Listen on specific interface?

[wayneyaoo]

Hi,

Thanks for the great project. I'm trying to deploy the software on my baremetal VM (non-docker). But then I start the server via npm start, I notice that it listens on IPv6 "all interface" (:::17442). The "url" in default.json doesn't seem to be honored. How can I configure it to listen on specific interface? Also how can I enforce it to use IPv4 only?

Thank you very much!
