The black screen was my fault :(
I did a lil mistake. After setting up a other Pi with MMM and copying my config i had the same problem. So i was checking my config (no syntax error), and everything i could rember was, that i changed this:
var config = {
address: "localhost", // Address to listen on, can be:
// - "localhost", "127.0.0.1", $
// - another specific IPv4/6 to$
// - "", "0.0.0.0", "::" to lis$
// Default, when address config$
port: 8080,
address: "0.0.0.0",
ipWhitelist: [],
to this:
var config = {
address: ["localhost", "0.0.0.0"], // Address to listen on, can be:
// - "localhost", "127.0.0.1", $
// - another specific IPv4/6 to$
// - "", "0.0.0.0", "::" to lis$
// Default, when address config$
port: 8080,
ipWhitelist: [],
And that was everything and cost me a lot of time ^^
