I think it still running

after you (try) to stop node-red, can you check `ps -A | grep node-red` again.
`node-red-log` will show you last logs - doesnt mean it is running

↑ look at the last line
What does `ps -A | grep node-red` show now?

ok, just in case node-red is auto restarting, for now, lets disable the service...
```auto
sudo systemctl disable nodered.service
node-red-stop
```
wait 10 secs
```auto
ps -A | grep node-red
```
if you get a PID, kill it (use sudo if necessary)
wait 10 secs
```auto
ps -A | grep node-red
```
* * *
Also, just in case, what does `pm2 list` show?

This is why you have port 1880 occupied.
Stop that container.

Your flow credentials file is encrypted using a system-generated key.
If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.
You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

Yes, that is good / normal.
Now you need to find all mqttssl nodes and delete them, then deploy AFTER they are all gone.
* * *
Additional:
- Are you using `node-red-contrib-usb`? If not, please uninstall that also.

With mqttssl the situation is the same like mqtt-env.
About `node-red-contrib-usb`- i wish to connect xbee modules via usb, so i assume that i need it?

No, you would typically use a separate application called zigbee2mqtt (installed to PI, not node-red) - then you communicate to the zigbee devices via MQTT or [node-red-contrib-zigbee2mqtt (node) - Node-RED](https://flows.nodered.org/node/node-red-contrib-zigbee2mqtt) - so no, you dont need the USB node.

Can you share your flows

This is interesting, but how is better/easier to physically connect xbee to rpi- via usb or jumper wires?
Can't send the full clipboard, because it is too big. I can send pics of the flows, if you want?

@Steve-Mcl : xbee !== zigbee

ah, my bad.
then I can help no further I'm afraid.
I would suggest you clean up your flows, get node-red running smoothly then try installing the nodes you need one at a time & checking node-red still works. Post errors as and when they happen.

If you mean, that xbee !== (inequality) zigbee. In my case they are equal (xbee module contains zigbee protocol).
