Hello,
I am facing an issue with the first time installation of Home Assistant OS on Raspberry PI 4.
I have flashed the latest OS 9.4 on a SD Card and connected the RPI directly to the router through an ethernet cable.
The web GUI is showing "Preparing Home Assistant" and stuck.
A supervisor log stating 'Updater.fetch_data' blocked from execution, no supervisor internet connection.
Thanks for your support in advance to solve this issue.
There was a problem with the internet reachability to home-assistant.io server. I had to use a VPN connection and the installation went smoothly.
