Google Assistant can't connect to Google on every restart

The problem

Since 2021.7.0b0 I find this error in my logs at every single restart of HA:

2021-07-02 09:08:46 ERROR (MainThread) [homeassistant.components.google_assistant.http] Could not contact https://homegraph.googleapis.com/v1/devices:requestSync

I can trigger the sync manually from HA services and from my phone without any problems showing. I do see DNS requests for those syncs, but I do not see a DNS request for the one throwing the error (possibly meaning it doesn’t even leave the box/container).

I am using a manual setup of Assistant (not Nabu Casa).

What is version of Home Assistant Core has the issue?

core-2021.7.0b0

What was the last working version of Home Assistant Core?

core-2021.6.6
