Addition: mmpm log shows this.
No errors in pm2 log.

Excerpt from my config:

var config = { address: "0.0.0.0", // Address to listen on, can be: // - "localhost", "127.0.0.1", "::1" to listen on loopback interface // - another specific IPv4/6 to listen on a specific interface // - "0.0.0.0", "::" to listen on any interface // Default, when address config is left out or empty, is "localhost" port: 8080, ipWhitelist: [], // Set [] to allow all IP addresses

This is mmpm log:

@Fozi thanks! It’s definitely been a lot of fun to work on, and hopefully a lot of people will find it fun to use
