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

```auto
pi@TimePi:~/.node-red $ sudo systemctl status nodered.service
● nodered.service - Node-RED graphical event wiring tool
   Loaded: loaded (/lib/systemd/system/nodered.service; enabled; vendor preset: enabled)

Mar 14 18:47:44 TimePi systemd[1]: Stopped Node-RED graphical event wiring tool.
pi@TimePi:~/.node-red $

```

How do I start NR is SAFE mode?

Searching it I get vague replies.  
Sorry.

Also, adding to my confusion:

If I am in a terminal and try to run NR this is what happens:

```auto
pi@TimePi:~/.node-red $ node-red
-bash: node-red: command not found
pi@TimePi:~/.node-red $ 

```

Thoughts?

This is worrying.

This is after a reboot too.

</div>

And a bit more....

Until a few minutes ago when i was editing the flow things worked....

Yes it is "old" but it works.

If I type `node -v` I get back 14.21.3` which is a bit of a worry - in some ways - though I don't really know why.

It is running on the _original_ dashboard.  
It is a RasPi 3 B +  
running buster.

I tried copying an older back up (from yesterday) and it still refuses to _run_.

if I try to run NR, I just get back a `command not found` error.

How broken is it?

Did you update npm? If so then you have ended up with a version of npm that won't run on your old version of nodejs.

I suggest that you run the node-red upgrade script to get back into a sane situation.

Make a backup of your flows file first, just in case.

[Edit] Don't run the upgrade script if you are running a version of the pi os older than buster.

First ensure it's stopped `sudo systemctl stop nodered` (you can add .service but it makes no difference)  
Start in safe mode` node-red --safe` NB node-red has a hyphen.  
The terminal output confirms it's in safe mode:

```auto
14 Mar 08:46:39 - [info] *****************************************************************
14 Mar 08:46:39 - [info] Flows stopped in safe mode. Deploy to start.
14 Mar 08:46:39 - [info] *****************************************************************

```

You can't use the terminal for anything else until you ctrl c, which will stop Node-red.  
So then `sudo systemctl restart nodered` (no hyphen)

I didn't change NPM between the deploys.

(I'll read the other reply now)

Well, I'm not sure if it is or not stopped.

Though I'm guessing it is stopped.

```

(and the machine has been rebooted.)

I can't start it as it says there is no such command and that NR is _not fully installed_.

```auto
pi@TimePi:~/.node-red $ node-red
-bash: node-red: command not found

```

OK, looking at your screen capture, `node-red` command is not found.

I'd make a backup of my flows then follow the advice to re-run the install script.

I have a few listed as the one needed.

(Yes, my fault for not keeping them correctly identified.)

This one?

`bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)`

Yes.  
Might be worth checking your node.js version with `node -v`.  
If it's less than v20, make sure the script updates it by appending --node20

```auto
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered) --node20

When backing up, these are the only files to back up - yes?

 ![Screenshot from 2025-03-14 19-59-50](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/3/4/344bfcd52d69841eb7e4073ca97411c60ebc2770.jpeg)

It has (from memory) worked like that.

I stop NR, delete the existing, and then copy the _backups_ to the NR directory.

You should backup the whole .node-red folder except for the node\_modules folder.

What kind of Pi is it? I find the install script takes about 5 min on any Pi with a quad core processor and 64 bit OS.  
The script is interactive, should tell you how far it's got.

Oldish.

It is a RasPi 3 B +

It is running on the original dashboard.

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.
