Sorry for feeling presure, but you made it again! Works like a charm!
Once again Thank you!

No worries mate. I’m glad you’re up and running again!

but I couldn’t get it right. So I hope you can.

That’s a lot of pressure. :^)

Try this at the very beginning of your config.js file, so it looks like this:

var config = {
	port: 8080,
        address: "0.0.0.0",
	ipWhitelist: [], // Set [] to allow all IP addresses.

After I followed your help step by step the mirror appeared again, but I was suprised when I put all my modul folder into the “new mm”, that together with the old config. file everything worked out fine.

You got lucky. The step by step says one at a time. I’m just saying. :^)

DeprecationWarning: sys is deprecated. Use util instead.

Probably, one of the modules you are using has a dependency that is outdated or no longer supported. It has nothing to do with the MM software. You can ignore that warning.

and the second thing is, that I can`t find the Remote control funktion on my mobile phone, as I found it bevor. Here is the part of my config.
Is there the “0.0.0.0” in ipWhitelist missing, and if yes, where to put it?

This has been discussed lately on the forum. Do a search by clicking the little magnifying glass, top right of the forum window. If you can’t find an answer, come back here and tell me.

var config = 
{
	electronOptions: {
		
	},
	  ipWhitelist: [
		"::fff:0.0.0.0/1",
		"::fff:128.0.0.0/2",
		"::fff:192.0.0.0/3",
		"::fff:224.0.0.0/4",
		"127.0.0.1",
		"::ffff:127.0.0.1",
		"::1"
	],

To get things right: first thing is to rename the MagicMirror folder.

Yes, but then I suggest you do a manual installation. If you run the automatic installer script you may run into trouble again.

Rename your MagicMirror folder. Go to https://github.com/MichMich/MagicMirror and click on the green Clone or download button on the right
side of the window, then click on Download ZIP. Now you have a MagicMirror-master.zip file. Double Click the file. Inside is the MagicMirror-master folder. Move that file to your /home/pi folder. Rename that folder to MagicMirror. Then in your terminal, cd into the MagicMirror directory and run npm install. When that finishes, run npm start, also in the MagicMirror directory.

At this point the mirror should run but you’ll likely get a “Create a config” message displayed. At which point you should do this.
https://forum.magicmirror.builders/topic/4528/how-to-create-a-working-config-for-absolute-beginners

Then back to your terminal, in the MagicMirror directory, run npm start. That should get your mirror running.

Then you can copy your modules, 1 by 1 into the new MagicMirror/modules folder and the entries into your new config.js file.

That should do it.

if I understand correctly your mirror doesn’t show up despite your pm2 “starting” it successfully!?

the run-start.sh shell script seems to be the problem.
This is the content:

if [ -z "$DISPLAY" ]; then #If not set DISPLAY is SSH remote or tty
	export DISPLAY=:0 # Set by defaul display
fi
electron js/electron.js $1

I would assume electron has some problem starting…

anyone else has an idea to get my mirror back on the screen again?

Until you can fix your updated installation, you can rename your MagicMirror folder and manually install the version of MM that was working for you. At least you’ll have your mirror back

DISPLAY=:0 npm start
