Hi,

I am a Node-RED user and I use it regularly, although I haven't been able to access Node-RED for a few days, since I get the following error:

```

And when I "sudo systemctl status nodered.service", I get that the service is constantly activating.

Anyways, I can run 'node-red' and it works. So, it is the service that it doesn't, but that is what I want.

I don't know if it's a coincidence or not, but these days I've updated to version 2.2, and I've also installed FlowForge on my computer.

Could you help me please?

Thank you,

Q.

This is also what I see when I run:  
sudo systemctl status nodered

```auto
● nodered.service - Node-RED graphical event wiring tool
     Loaded: loaded (/lib/systemd/system/nodered.service; disabled; vendor preset: enabled)
     Active: activating (auto-restart) (Result: exit-code) since Thu 2022-02-17 11:06:54 CET; 3s ago
       Docs: http://nodered.org/docs/hardware/raspberrypi.html
    Process: 20636 ExecStart=/usr/bin/env node $NODE_OPTIONS red.js $NODE_RED_OPTIONS (code=exited, status=1/FAILURE)
   Main PID: 20636 (code=exited, status=1/FAILURE)

```

If it helps!

What h/w and OS are you using and how did you install node-red?

Post the log from before the error you show, starting from the Welcome to node-red message. Depending how you installed node red you may be able to get the log in a terminal using  
`node-red-stop`  
`node-red-start`

Thank you Colin, but finally I solved it by going to the **/lib/systemd/system/nodered.service** and commenting the

`#ExecStart=/usr/bin/env node $NODE_OPTIONS red.js $NODE_RED_OPTIONS`

and discommenting the:  
`ExecStart=/usr/bin/env node-red-pi $NODE_OPTIONS $NODE_RED_OPTIONS`

Thank you anyways!

Had you previously changed it? What you have now is the default file contents.
