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.Tls11;

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

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

do you already tried ws.SslConfiguration.EnabledSslProtocols = System.Security.Authentication.SslProtocols.Tls12; In my case this fixed the error

Thanks that one worked for me! In my case I wanted to connect to a websocket server, which supported v1, v1.1 and v1.2, on Ubuntu 20 but failed with no protocol available. The same (.NET 5) application worked on Windows 10.

Did also work for me. Thanks a lot!
