Erreur: Invalid client id lors de la connexion avec Google Home

Hi all,
I followed the conf procedure for manual Google Home integration. On the Google side everything seems OK, however when Google Home tries to connect I get the following error in the log file:

2023-09-26 16:08:07.586 WARNING (MainThread) [homeassistant.components.http.ban] Login attempt or request with invalid authentication from (

And Google Home displays the log page but it displays the following error:

warning: You are about to give access to PROJECT_NAME_GH to your Home Assistant instance.
error: Invalid client id

I think it comes from the cache but I don’t see how to remove it. I have the same problem with Android and IOS.


English only please.
