One more data point, I just formatted an SD card with Ubuntu on the raspberry PI. Then I tried the 'sudo apt upgrade' and received no errors. I also tried the same command from Raspberry PI OS using a hotspot on the phone and again no errors. So it seems like there is something in the combination of Raspberry PI OS and my router that is blocking access. Remove the router and Raspberry PI OS works. Keep the router and the PI but replace Raspberry PI OS with Ubuntu and it works.
