Node RED addin setup

Hi a beginners question

I installed HA OS this weekend on QNAP as a VM. I have added Node RED but it does not start - from what I have read this should be simple to fix add a cert or change ssl in the config file

But I have no idea where the node RED config is - the example seem to have json or docker compose any pointers would be appreciated

If you installed it from the HA Addon Store, then the config is in the Addon Settings. Just click on Supervisor, Addons, NodeRed and then Configuration.

so obvious when I look in the right place - hard to move from terminal

Thanks
