ConnectionRefusedError: [Errno 61] Connection refused since v2.4.0

[kwadsten]

Hi,

I recently updated my arduino libraries to the latest versions and now my websocket server no longer accepts connections.

I am serving a webpage and creating a websocket server on my ESP32 (NODE32S) and accessing it through my iPad and madOS.

It works fine with v2.4.0 but not with v2.4.1 or higher.
If I go back to v2.4.0 it works again.

I am not using any sort of SSL or secure connection. My esp32 app creates a webserver (on port 80), serves a webpage and starts a websocket connection (on port 8001).

Any ideas?

I'm getting a ConnectionRefusedError: [Errno 61] Connection refused error on the iOS/macOS side (Safari, firefox, chrome all cannot connect).

because i have not chance to post new issue about my example with pico2040 + W5500 lan chip jack plugin will post it here. apologize to this mate that is first post, but need urgent what to do about it. i make a server board that need to use web socket with web site in file systen for pico with lib of earl philpower III
and find this lib for webs socket but it is closed only for wifi like i see in compiling
here is error i receive when try to compile

i don know how to do it with this lib or just need some other. and can this lib will be make it to work with wired w5500 hardware with ethernet lib from https://github.com/earlephilhower/arduino-pico lib. thanks
