My ESP-F Devkit V4 board with an ESP-f module keeps resetting / crashing when a webpage that it's hosting is accessed. Previous projects that were working , now don't. The module connects to the wifi no problem
and all seems ok until you try and access the hosted webpage then it crashes. If I host a basic page is seems to be ok , but anything more complex causes a crash. I've tried 3 modules , same problem. The code that I got from this page used to work , now crashes:
https://circuits4you.com/2018/02/04/esp ... efreshing/

Any ideas?
I thought it may be a configuration issue in the IDE , but I've had no luck resolving it.

This is the error I'm getting from the console:

Managed to resolve the issue.
When I reverted the software in the board manager to "ESP8266 community 2.6.1" from 2.6.3 the problem goes away. 2.6.2 and 2.6.3 both crash , so there must be some issue with these libraries.
Cheers

- Thu Feb 18, 2021 8:11 pm #90577 I have the same issue.. When I roll back the board to version 2.6.0 the code works.. Anything higher and no go.. The little guy crashed when pulling a web request.
