I was editing an existing flow and suddenly when I DEPLOYED I got a "server not responding" error. This is what I get when testing the status of NR pi@TimePi:~/.node-red $ sudo systemctl status nodered.service ● nodered.service - Node-RED graphical event wiring tool Loaded: loaded (/lib/systemd…

I realise it isn't that, nodejs 18 is the latest supported for buster, so re-run the script but with --node18 instead of 20

This sort of worries me: WARNING: apt does not have a stable CLI interface. Use with caution in scripts. It is in a CLI/Terminal on the machine.

Well Debian Buster is kind of out of date. How much stuff besides Node-red do you have on the Pi? Perhaps it's worth a fresh install, maybe on a new Sandisk Ultra micro SD. Install Node-red then copy (at least) the flows and flows_cred files from your backup.

I hope the SD card isn't on it's way out. Haven't had any other problems. I was just .... stupidly ..... trying to get a bit of code working.

It is kind of the ...... main machine.
