Error: MagicMirror will not quite

[e199504]

Hello,
I have installed MM from here

When I want to run the Magic Mirror, I am getting the following error

"MagicMirror will not quit, but it might be good idea to check why this happened. Maybe no internet connection? "

pi@raspberrypi:~/MagicMirror $ DISPLAY=:0 npm start

> magicmirror@2.15.0 start
> ./run-start.sh $1

@e199504 did u say yes to pm2?
then pm2 is already running mm.

do

pm2 status

then
pm2 stop all, or 0, or the name shown in the pm2 status command output
