Problems restarting MagicMirror (Port 8080 in use ...)

[MichMich]

I’ve recently reinstalled my Pi and installed the latest built of the develop branch.
I have a small update script which eventually restarts MagicMirror using pm2 restart mm.
Unfortunately, it won’t restart because it says port 8080 is already in use.

The only solution is rebooting the Pi.

Before I spend some time on solving this, I’m curious: does restarting work on your pi? And are you running the latest develop branch as well?

Hi! Yes, restarting works. This usually happens when a module has failed to work (have some error in it). Even though you fix the problem, as long as you have not restarted it seems the port still is “in use”.

By the way, thank you for this GREAT project!

Best regards Snille

Here I was thinking it was just me LOL No biggie restarting seems to solve it.
So until it gets figured out we’ll live with it

@cowboysdude Ah, so you’re experiencing the same? In that case it’s worth diving into …

@MichMich I’m not running the develop branch, but I do know the background off the feedback (port 8080 is use). I’m not sure if your looking for this information, other ways let me know.

Same for me, if you mean this Messages (I’m using the main 2.1):

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
If you think this really is an issue, please open an issue on GitHub: https://github.com/MichMich/MagicMirror/issues

Ups, there a bug for pm2 config. I pushed a fix
https://github.com/MichMich/MagicMirror/pull/640

The restart is work for me. Are you try stop/start?

By the way, there a interesting notice in restart process by pm2

Restarts are now immutable, to update environment or conf use --update-env

Here I’m using 2.1.5 version

pi@raspberrypi:~/MagicMirror $ pm2 -version
2.1.5

@roramirez said in Problems restarting MagicMirror (Port 8080 in use ...):

pi@raspberrypi:~/MagicMirror $ pm2 -version
2.1.5

Do I need pm2?

pi@MagicMirror:~ $ pm2 -version
-bash: pm2: Kommando nicht gefunden.

(translates: command not found)

@roramirez what i have to do to get the fix from github? I have installed MM v2.1.0

[MichMich]

This seem to have fixed the issue. Thanks @roramirez!
