My Supervisor has no Internet

Hey!

I’ve tried to make a fresh Install HA on a new Raspberry Pi4 B this week.
I’ve used the Raspberry Pi Official Imager since I’ve had a few problems with balena etcher…

I can acces HA at homeassistant.local:8123 but each time I have an error.
The error is that my supervisor has no internet acces.

I’ve tried lots of things but I still can’t get it to work.
Because of this, I can’t install HA…

This is what I get told: [supervisor.jobs] 'Updater.fetch_data' blocked from execution, no supervisor internet connection 22-03-15 12:00:22 WARNING (MainThread) [supervisor.homeassistant.core] Error on Home Assistant installation. Retry in 30sec

Can you help me please ?

Is it plugged into a lan?
