Google Nest Integration not working (google api oauth timeout)

Hello,

I try to add the Google Nest integration in Home Assistant.
I do the whole procedure on this page: https://www.home-assistant.io/integrautions/nest/
It worked a few weeks ago, but it hasn’t been working for a while.

However, at one point I have an error: Timeout Resolving Oauth Token

It is to finalization.

Home Assistant is in a proxmox container.

It is possible that the concern has occurred since I passed on Proxmox, but I am more certain.

I have redone all the steps several times, but I still block at the same time: Timeout Resolving Oauth Token (the very last step).

My assistant home is up to date.

I also tested all the solutions I have found on the forum, but nothing works.

Do you have an idea ?

Thanks in advance

Solved, just desactivate ipv6 on ha settings :

(HA UI → Settings → Network IPv6 → Deactivate)
