you should check if your moonraker is running and if not, why this is happening.
Connect to your printer using ssh and run
to see if moonraker is even running.
Then you can take a look into the logs to determine why not, or if anything other is preventing it from being accessed.
To do that, run
Code:
journalctl -u moonraker.service --pager-end
Please post the output of both commands and the contents of your ~/printer_data/config/moonraker.conf file, then we can maybe see what is going on.
Do you know from which versions you started the upgrading and to which version you now upgraded?
