Apple TV on WiFi but no internet

For two years everything was working fine. Now my 4K Apple TV is connected to my home wifi (showing IP address, MAC, signal strength, etc in Settings on AppleTV), but it is not connected to the internet. On my Google Home router app I see the Apple TV is connected but zero data going through. I’ve logged out, restarted and un plugged the router and Apple TV multiple times. I even reset the router back to factory settings and re setup the mesh network. Apple TV is up-to-date on software. personal hotspot from my phone (on 4G) and Apple TV works. I suspect it’s a setting somewhere. Any help would be greatly appreciated.
