Hi forum.
Not sure whether this is hardware-related, but I'm not able to see my node-red run on boot all the times i boot it. It dows a good 50% of times (I'm afraid too unreliable).
I'm on the latest raspby OS and on Raspberry pi 4.
Based on this thread, I did:
run
pi@raspberrypi:~$ sudo systemctl status nodered.service
● nodered.service - Node-RED graphical event wiring tool
Loaded: loaded (/lib/systemd/system/nodered.service; enabled; vendor preset: enabled)
Active: inactive (dead) since Fri 2020-08-21 15:59:37 CEST; 10min ago

Process: 357 ExecStart=/usr/bin/env node-red-pi $NODE_OPTIONS $NODE_RED_OPTIONS (code=killed, signal=INT)

Aug 21 15:59:37 raspberrypi systemd[1]: nodered.service: Succeeded.
if I run
pi@raspberrypi:~$ node-red-log
Started Node-RED graphical event wiring tool.
nodered.service: Main process exited, code=killed, status=2/INT
nodered.service: Succeeded.
pi@raspberrypi:~$ node-red-start
Start Node-RED
Once Node-RED has started, point a browser at http://192.168.8.111:1880
On Pi Node-RED works better with the Firefox or Chrome browser
Use node-red-stop to stop Node-RED
Use node-red-start to start Node-RED again
Use node-red-log to view the recent log output
Use sudo systemctl enable nodered.service to autostart Node-RED at every boot
Use sudo systemctl disable nodered.service to disable autostart on boot

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.
