Dashboard doesn't load anymore

My dashboard now just shows me the default welcome screen asking me to deploy nodes (" Welcome to the Node-RED Dashboard
Please add some UI nodes to your flow and redeploy.") , but it was working still few days ago and has worked for months without any maintenance. Node-red is starting without error and I can access the interface, it's just the dashboard that doesn't work.

From the log it says the dashboard is started at /ui

---------------------------------------------------------------------
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.

What else should I look at?

That shows you are running as root user. Is that correct ? I would expect you to be running as user pi.

Hello,

Thanks for the fast reply. Yes it seems it is ran as root... and I don't remember why. I made this installation as a test and it was working so good that it became a full prototype and soon production :smiley:

Might have to do with the fact that I'm located in China and I couldn't do the recommended install at the time that retrieve content from Github thus I went another way.

Anyway, today I'm back to work, and it just loads totally fine... I don't really like the problem that solve by themselves without any idea where the trouble came from but it's not a critical system for me so I'll be happy with it this time.

Topic closed... for now.

Have a good day!
