what is exception -203 ??

[2003emachinesDesktop]

i have a micropython project running on an esp32. im using microdot for a webserver.

i have a try/exception structure in my code, and sometimes when i start the webserver or try to connect to it via a browser, i am getting -203 as an exception.

looking on the wider internet, but also searching within the discussions here on github and no one seems to know what -203 means.

im faily certain its not a microdot specific issue, per se, as other users using different webserver libraries or frameworks are also getting -203. perhaps its from an internal modual that both microdot and other webservers are using.

very curious as to what -203 means, as ive been stuck with this nonfunctional project for a week now.

This is an ESP-IDF error code. Search internet for esp-idf wifi error 203 and you may find something like:

ESP-IDF Wi-Fi error code 203 (or WIFI_REASON_ASSOC_FAIL) means the ESP32 successfully found the router but failed to complete the association phase. This usually happens due to incorrect WPA2/WPA3 credentials, router incompatibility, or weak signal strength.

For a complete list of ESP-IDF error codes see: https://docs.espressif.com/projects/esp-idf/en/v5.4.2/esp32/api-guides/wifi.html#esp32-wi-fi-api-error-code
