Node-red won't start on home assistant, how to fix it?
Not many people here use HA so this is question normally best asked on their forum
Do you have "Start on boot" enabled for the Node Red plug-in in Home Assistant?
yes, start on boot is enable but node-red won't started on boot or try to run it manually
In addition to "Start on boot," one has to click the "start" link in the plug-in. The plug-in also has a "log" link you can click to see what the plug-in is doing.
If none of that helps you, I would take the suggestion of cymplecy and move your question over to the Home Assistant forum. I suspect someone will ask to see system logs regarding your problem, a process I am not very familiar with.
