For what my opinion is worth (i.e. trying to make a remote relay module with the async library) - this addresses the changes needed to fix for the 3.x version of Arduino core for ESP32.

also just anecdotal, but after getting error: 'mbedtls_md5_starts_ret' was not declared in this scope; did you mean 'mbedtls_md5_starts'? and similar errors, using this fork works great with my ESP32-S2-WROVER boad

I don't see code to initialize your wifi client? I can assume it is lower but I hate making assumptions if this is partial code. I'm assuming as well that if you do have the wifi initizlized that is outputting the IP address to serial output? Also: Same network or different VLANs (if applicable)?

@Evs91 the issue was that I was declaring AsyncWebServer server(80); inside the function's scope. At the end of the scope the object is gone. After moving it to outside, in the global scope, everything worked as expected.

Same error message here :-(
I've selected the board "ESP32 Dev Module" in Arduino IDE and use a "ESP-32 Dev Kit C 2" from AzDelivery.

What can I do?

Thank you, this is working for my setup

[mnemocron]

Heya, I just crashed into the ol' issue of mbedtls_md5_starts_ret was not declared in this scope. Maybe someone could actually merge this PR (?)

[giddel]

Yes, please merge 😗

Use the ESPAsyncWebServer regular maintained by Mathieu Carbou.
https://github.com/ESP32Async/ESPAsyncWebServer
it can also be found between the Arduino libraries in the Arduino IDE
