It works in Maui but not in Xamarin

[TesterNow]

I am using the nuget in version 3.0.6
I created a new project in Xamarin forms with the following code in the MainPage constructor, but it doesn't work.
It stays in a loop reconnecting.
I did the same in a new project in Maui .NET and it works !

I don't understand what's going on, it should be compatible with Xamarin forms

Does anyone know what's wrong?

Code:

public MainPage()
{
InitializeComponent();

    var socketIOOptions = new SocketIOOptions
    {
        Reconnection = true,
        ReconnectionAttempts = 5,
        Transport = SocketIOClient.Transport.TransportProtocol.WebSocket
    };

    var io = new SocketIO("https://example.com/", socketIOOptions);

    io.On("seq-num", e => Console.WriteLine(e));
    io.OnConnected += async (s, e) => Console.WriteLine("Connected!");
    io.OnDisconnected += async (s, e) => Console.WriteLine("Disconnected!");
    io.OnError += async (s, e) => Console.WriteLine("Error!");
    io.OnPing += async (s, e) => Console.WriteLine("Ping!");
    io.OnPong += async (s, e) => Console.WriteLine("Pong!");
    io.OnReconnectAttempt += async (s, e) => Console.WriteLine("Reconnecting!");
    io.OnReconnected += async (s, e) => Console.WriteLine("Reconnected!");
    io.OnReconnectError += async (s, e) => Console.WriteLine("Reconnect Error!");
    io.OnReconnectFailed += async (s, e) => Console.WriteLine("Reconnect Failed!");

    io.ConnectAsync();

    Thread.Sleep(10000);

}

Could you help me @doghappy ? it's a simple example but it doesn't work in Xamarin

Or does anyone have an example?
