Cannot access MM2 across the network - localhost ok

[dangerousden]

Hi All. I have been using computers for a long time, and have recently taken the jump into Linux. My wife started my interest with the MagicMirror project.

So far all has been great. I’ve install the MM2 v2.33 and had it running. I’ve added modules and all was good. Testing on the Pi was fine, and I would even access from my Laptop. However, I have made some silly mistake somewhere, which only became apparent when I rebooted. I cannot access from the IP any longer. localhost on the Pi still works, but Modules like FormulaOne and getting my Gmail calendar just sit “loading”. All was good before the reboot.

Can anyone offer any suggestions?

I’ve checked config.js and the IP is blank, and IPWhitelist is blank (unchanged from before the reboot)

On starting the MM

There seems to be an error, but it isn’t giving me any pointers

Many thanks for any help

This module configuration contains errors:

you have a bad config.js, and it started with the default which is not outside enabled…
can you post your config.js , make sure to xxx out any personal info, apikeys or calendar urls…
use the code block

before posting do this

cd ~/MagicMirror/config
node -c  config.js

see if that provides a better error messsage

@dangerousden this error is reported when there are 2 commas in a row between modules

      },,
      {
          module: "foo",

the next release shows this error in detail,

 Your configuration file contains syntax errors :(
Line 1726 column 9: Unexpected comma in middle of array.

node -c doesn’t report it
