Error on Node red install

Third party integrations Node-RED
1

I have a new HAOS install

  • Installation methodHome Assistant OS
  • Core2026.8.1
  • Supervisor2026.07.5
  • Operating System18.2
  • Frontend20260729.6

It is running on a Raspberry Pi4 with 4Gb RAM

I am trying to install Node Red via Settings>>Apps The node red version is 22.0.1

Node red appears to install but when I press start it displays ''Starting" briefly then the rather uninformative message “Error”

There is no message in the Notifications log.

This a clean install on new hardware, no flows or any configuration of node red and minimal configuration of HA

Any thoughts?

You noticed that besides start there’s also a button for it’s configuration?
Not to mention one for log? Perhaps you could provide some more information?

Post the log from the app page.

Edit: you may have ssl enabled by default. On the config page of the app, switch off ssl, save and the app will restart.

Thanks for pointing out the log file; I was looking for a HA log not a Node Red log.
The issue was SSL:
[13:28:42] FATAL: SSL has been enabled using the ‘ssl’ option,

[13:28:42] FATAL: this requires an SSL certificate file which is

[13:28:42] FATAL: configured using the ‘certfile’ option in the

[13:28:42] FATAL: app configuration.

[13:28:42] FATAL:

[13:28:42] FATAL: Unfortunately, the file specified in the

[13:28:42] FATAL: ‘certfile’ option does not exist.

[13:28:42] FATAL:

[13:28:42] FATAL: Please ensure the certificate file exists and

[13:28:42] FATAL: is placed in the ‘/ssl/’ directory.

[13:28:42] FATAL:

[13:28:42] FATAL: In case you don’t have SSL yet, consider getting

[13:28:42] FATAL: an SSL certificate or setting the ‘ssl’ option

[13:28:42] FATAL: to ‘false’ in case you are not planning on using

[13:28:42] FATAL: SSL with this app.
This was resolved by switching SSL off in the configuration screen
