Exception while hosting secured websocket

Hi,

I tried to start websocket server in secured mode on localhost. For generating self signed certificate I used Pluralsight library (http://blog.pluralsight.com/selfcert-create-a-self-signed-certificate-interactively-gui-or-programmatically-in-net). Here is my code:

public void Start()
    {
        var server = new WebSocketServer(51002, true);
        server.Certificate = GenerateSelfSignedCertificate();
        server.AddWebSocketService<StatisticsListener>(@"/Stats");
        server.Start();
    }

    private X509Certificate2 GenerateSelfSignedCertificate()
    {
        using (CryptContext ctx = new CryptContext())
        {
            ctx.Open();

            X509Certificate2 cert = ctx.CreateSelfSignedCertificate(
                new SelfSignedCertProperties
                {
                    IsPrivateKeyExportable = true,
                    KeyBitLength = 4096,
                    Name = new X500DistinguishedName("cn=localhost"),
                    ValidFrom = DateTime.Today.AddDays(-1),
                    ValidTo = DateTime.Today.AddYears(1),
                });

            return cert;
        }
    }

Here is the exception thrown by webserver:

This exception occurs even when I try different ways to generate a certificate or websocket clients. Could you tell me what is the cause of this error?

Start by reproducing the secured localhost server using the certificate-generation code in the issue. Read websocket-sharp/Ext.cs around EqualsWith, HttpBase.cs around readHeaders, and TcpListenerWebSocketContext.cs around the failing request path. Done means identifying the cause of the exception and documenting or correcting the secured WebSocket handling.
