Will test, have you tried a full erase?

GodisGod commented 7 months ago

same question

real-bombinho commented 6 months ago

I hit the Exception (3) as well on some older NodeMCU1.0 boards but not on the ESP01 and D1 mini.

It seems to be raised due to no established connection on a first glance. Albeit the NodeMCU projects are some legacy projects, nursed along with little remaining memory.

ESP01 and D1 mini use lesser memory and have less web dependent functionality.

I got the same issue, by using me-no-dev's esp exception decoder I got below result

Board : D1 Mini (says ESP8266MOD) Error : same as OP - error Exception (3) occurs when calling AP webpage

jay6621 commented 6 months ago

with board manager url http://arduino.esp8266.com/stable/package_esp8266com_index.json and esp 8266 board version 3.1.2 solves issue for me leaving with another library's issue.
