Yes, I am a NOOB. But I do have some programming background. I recently installed MM 2.6.0 on a pi 3B+. Additionally, I installed the MMM-Admin-Interface module. While logged in via VNC to the pi, the program works fine. However, if I try to access the mirror on another computer (http://192.168.1.19:8080/MMM-Admin-Interface) I get the above mentioned error. My config file is pretty straightforward. I have tried every option that I have found, but still no luck. My .PM2 log has no errors. Any suggestions would be appreciated.

The following is from my config.js file.

var config = {

address: "",

// address: “127.0.0.1”, // 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, is “localhost”
port: 8080,
address: [“0.0.0.0”],

// ipwhitelist: [“192.168.1.9”,“::1”],
ipwhitelist: [],
// ipWhitelist: [“127.0.0.1”, “::ffff:127.0.0.1”, “::1”], // Set [] to allow all IP addresses
// or add a specific IPv4 of 192.168.1.5 :
// [“127.0.0.1”, “::ffff:127.0.0.1”, “::1”, “::ffff:192.168.1.5”],
// or IPv4 range of 192.168.3.0 --> 192.168.3.15 use CIDR format :
// [“127.0.0.1”, “::ffff:127.0.0.1”, “::1”, “::ffff:192.168.3.0/28”],
