This my exeption track. if i try send http requests to websocket handhskake, all ok 101 But if i try connect to wsSharp, i get Exeptions MY CODE:

using (var ws = new WebSocket("wss://ws-gate.fxclub.org/ws")) { 
//ws.SslConfiguration.EnabledSslProtocols = System.Security.Authentication.SslProtocols.Tls13;

        ws.OnMessage += (sender, e) =>
                    Console.WriteLine("Laputa says: " + e.Data);

        ws.Connect();
        ws.Send(secWebSocketKey);
        Console.ReadKey(true);
    }
