Hello everyone,

I've had the problem for a few days that my Node Red addon in the Home Assistant no longer starts.

Everything was actually quite simple until now. I installed the addon, started it and everything worked.

I'm not a complete beginner when it comes to Home Assistant and setting up various addons or HACS. But as soon as I have to make settings in a shell or console, I have to go through tutorials

It would be great if I could get information or even better help this way.

I have uninstalled the addon, reinstalled it, tried to start it in safe mode, but I get the same error message for everything.

I get the following error message from the log:

That usually means that node red is already running, but whether that is true when used with H A I don't know.
