WebSocket Client Sample for LILYGO board

[JpEncausse]

Hello,
I try to connect a Websocket Client on LILYGO board to a Websocket Server.
I use the following library Links2004/arduinoWebSockets but it fails on all the board. Here write a StackOverflow question.

[122264][E][WiFiClient.cpp:517] flush(): fail on fd 48, errno: 11, "No more processes"
[WSc] Disconnected!

I search in the Xinyuan-LilyGO repository for any sample but I only find WebSocket server implementation.
Is there some limitation that prevent LILYGO board to connect to a WebSocket Server and receive remote commands ?
Thanks ! I'm stuck
