ESP32 web server; creates WiFi channel but does not load web pages

Postby campinLOU » Fri Feb 03, 2023 6:26 pm

ESP32 web server; creates WiFi channel but does not load web pages; changing channel did not fix problem; changing IP address, still not loading web pages on either cell phone or laptop; Arduino 1.8.19, board manager esp32 2.0.5; ESP32-WROOM-DA Module, default 4MB, 240MHz, 4MB, core 1
