Stuck on Preparing Home Assistant page

I am trying setup a new fresh install of Home Assistant OS on my raspberry pi4 4gb but it never finishes preparing Home Assistant.

I tried with 2 MicroSD and tried both 64 and 32 bit version, various versions of hassio os (6.3, 6.2, 5.0) with the same results.
The raspberry is connected directly to my ISP router, I do not have pihole or similar
I tried to set a static ip address, an alternative dns (8.8.8.8 and 1.1.1.1)

By clicking on the blue dot, these errors on the log are repeated every 30 seconds
I can regularly access from the web page but it seems not to be connected to
internet

21-02-03 00:22:17 WARNING (MainThread) [supervisor.jobs] 'Updater.fetch_data' blocked from execution, no supervisor internet connection
21-02-03 00:22:17 WARNING (MainThread) [supervisor.homeassistant.core] Error on Home Assistant installation. Retry in 30sec

Anyone have any advice on how to fix this? I have been stuck on the setup for 4 days with no results
