<![CDATA[PM2 status online, but mirror doesn't start]]>Fresh install on a Pi 3 B+ using Sam’s install script (thank you - I particularly like the boot splash screen).

pm2 status shows the MagicMirror application as online, however no mirror appears on the screen. Browsing from another machine to http://ip:8080 gives connection_refused.

pm2 (red coloured) logs below:

Anyone spot anything obvious I can look in to?

The pi has been acting odd since the fresh install - SSH tunnel freezing and not even responding to pings. :worried_face:

Thanks in advance,
Matt

pm2 stop all
cd ~/MagicMirror
npm start

Pay attention to logs. In my case one of the modules was throwing an error. I removed the module folder, re-cloned it (including required npm install within the module folder) and then restarted the application with pm2 start MagicMirror.

see this for general process of fixing missing libs

the npm start generated a few errors relating to a particular module…

[06.10.2023 14:10.39.752] [ERROR] (node:2973) UnhandledPromiseRejectionWarning: /home/pi/MagicMirror/modules/MMM-MyCommute/node_modules/jsbn/index.js:647
    function

So I removed and re-added that. pm2 start MagicMirror got it going again.

Thank you again!

Matt

pm2 stop all
cd ~/MagicMirror
npm start

I suspect this
