I can’t find any recent info on the sync issue in Hass
I get the following in the logs when I try to sync
Request for https://homegraph.googleapis.com/v1/devices:requestSync failed: 404

I’ve also tried the following
but this gives the following response
{
"error": {
"code": 404,
"message": "Requested entity was not found.",
"status": "NOT_FOUND"
}
}
Other than that, Google Assistant seems to work fine and it able to control my devices.
It started with the expiry of the secure web certificate and ended up changing too much parameters. Anyway got stuck with above error until I grabbed my Google Home app and adding Home Assistant as a device again. Hope it helps you out.
I have the same error. Al devices are in the Google Home app Offline. Did a resync. Created a new service-account. Everytime the same error. I don’t use GoDaddy certificates but Let’s Encrypt with a HAProxy.
So did you allready try to link to HA again, this can be done in the Google Home app (same like you link to Spotify for example). Or add a new device, I’m not sure anymore - I think HA was detected and visible in the Google Home app and I was able to add it again.
