      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 :)

              @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.

                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
                Launching application.

                  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?

                  pi@raspberrypi:~/MagicMirror $ pm2 status MagicMirror

                  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

                    Do I need pm2?

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

                    (translates: command not found)
