Describe the bug

I tried to run the example of ESP32 called "Minimal-Esp32-Client" (and other examples, but this one is the easiest to reproduce), then the monitor printed

[ 4159][E][WiFiClient.cpp:313] setSocketOption(): fail on -1, errno: 9, "Bad file number"

and then Not Connected!

Steps to Reproduce

I am using visual studio code with PlatformIO and created a new project of ESP32 on Arduino framework. Just put the example code "Minimal-Esp32-Client" with your wifi ssid and password and the websocket server to connect to and it will do it

PlatformIO version: Core 6.1.4 - Home 3.4.3 Core Version: I am not sure, i think Arduino-mbed Board type: ESP32 Contextual information: I tried to run the example code Using Windows 10

When running in ArduinoIDE I still got the error message, but I could print more debug line 2

Do some basic research, test some more examples before posting any issue.

I'm closing the issue unless you prove this is a bug of this library.

As you're using ESP32, I suggest you post any issue next time in ArduinoWebsockets library
