Hi.
I trying to use this package but getting output message as shown on titile

`
/// Using a test's web socket echo server at: https://www.websocket.org/echo.html
[TestClass]
public class WebSocket4Net_UnitTest
{
private readonly string webSocketHost = "wss://echo.websocket.org/";
private readonly string echoCommand = "Hi, Kaazing! How are you?";

    private WebSocket websocket;

    [TestMethod]
    public void TestConnection_WhenPutCommandFirst_ExpectedCorrectResult()
    {
        //ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

        websocket = new WebSocket(uri: webSocketHost);
        websocket.Opened += new EventHandler(websocket_Opened);
        websocket.Error += new EventHandler<SuperSocket.ClientEngine.ErrorEventArgs>(websocket_Error);
        websocket.Closed += new EventHandler(websocket_Closed);
        websocket.MessageReceived += new EventHandler<MessageReceivedEventArgs>(websocket_MessageReceived);
        websocket.Open();

        while (websocket.State == WebSocketState.Connecting)
        {
            Thread.Sleep(500);
        }
    }

    void websocket_Opened(object sender, EventArgs e)
    {
        Debug.WriteLine($"Websocket opened");
        this.websocket.Send($"{echoCommand}");

    }

    void websocket_MessageReceived(object sender, MessageReceivedEventArgs e)
    {
        Debug.WriteLine($"Message received: {e.Message}");
    }

    void websocket_Error(object sender, SuperSocket.ClientEngine.ErrorEventArgs e)
    {
        Debug.WriteLine($"Error: {e.Exception.Message}");
    }

    private void websocket_Closed(object sender, EventArgs e)
    {
        Debug.WriteLine($"Websocket closed: {e}");
    }
}`

After some googling i found a possible solution but it isn't helped me.
I have tried to change target .Net framework for 4.6.2 also but got the same.

If to try with ws uri (webSocketHost = "ws://echo.websocket.org/") it will work. . I'm assumpting it may be related with some of TLS issue? Can you help.
