PicoPLus 2W webserver problem

I am haven’t been able to get a webserver running on the Pimoroni Pico Plus 2 W. I get the Wifi Connected message and the listening message, but neither my phone nor my windows laptop can connect to a web page at the ipaddress that micropython shows as its connection.

I have tried two different examples and neither work.

Any hints or pointers to known working micropython code?
