Mobile data works on Gmail but not on any browser on Pixel 4a 5G

I have a Pixel 4a 5G running on the latest Android 12 as of 7/22/22. With mobile data and background mobile data enabled in apps, I can make phone calls and check Gmail, and yet, no browser works: Firefox, Chrome, Duckduckgo. They spin or put a loading bar and eventually say "no network connection". I've reset the networks and reloaded the base system (system reset), but nothing changed. Any ideas?
