I had the same issue with my Google home.
But after '''updating my home address''', its work like a charm. Update your as well:
'''Open the Google Home''' app on your Smartphone → Tap on the '''hamburger''' → '''More settings''' → '''Google Account settings''' → Update '''Personal info'''.
If this solution does not work for you, then try some other fixes to [https://www.megebyte.com/google-home-mini-not-responding/|solve Google Home not responding problem].
