Cannot update to HA 7.1 OS

it’s a week I can see the update button in Configuration but the result is this:
2022-01-12 02:22:06 ERROR (MainThread) [homeassistant.components.hassio] Failed to to call /os/update - Can’t fetch OTA update from
But if I try to download the file I can. Is it possible to update from a USB key?
It’s not a space problem I have 450Gb free.
I’m using a RPI 4 and booting from an USB3 adapter and yesterday I updated with no issues to 2021.12.8

Go to the Supervisor System Page. In the Host box, click CHANGE next to your IP address and under the IPv4 drop-down list, make sure that your DNS server is set correctly. Or try or and see if that makes a difference.

Also check how much disk space you have available.

This is my actual config:

and about my disk space
/dev/sda8 has 410Gb free
any advice is welcome …

What version OS are you on now?

If you are on v5.x you may need to update to v6.x first. This can be done via the HA CLI.

ha os update --version 6.6

Then once that is complete (or if you are already on v6.6):

ha os update --version 7.1

Hi actually OS is 7.0
Trying your suggestion … via Terminal & SSH component
showing “processing…”
stay tuned!

I really don’t understand …
BTW I’m waiting a couple of new powerline I think they are the problem… well hope so …


… with new powerline …
I have no words … only bad words!
Thank you very much for your support.
