Help: Quest 3s game only loads while on mobile hotspot

My son's meta quest 3s will only load the game Animal Rivals while connected to mobile hotspot. It would work on our home network just fine until a couple days ago. When the game is selected, the load screen comes up and everything appears to be working fine right until he should be brought into the game. At that moment, the screen goes dark and a few seconds later an error message, something about client timeout. It opens and works just fine on at&t phone hotspot. I've tried restarting the 3s, restarting the router, and forgetting network and rejoining.

Our home network is at&t fiber with a Eero 6+ mesh network. Signal strength and speed are great. Since the problem arose, I search the web and tried making changes to our network through the Eero app, but to no avail. Current Eero settings: IPv6 on, DHCP & NAT automatic, DNS set to default, Local DNS caching off, UPnP off, SQM on, Client Steering on, Encryption: 2.4Ghz set to WPA2 and 5Ghz set to WPA3.

Any help would be greatly appreciated.
