Cannot establish WSS connection

[esso23]

Hi Elad,
I have a problem when attempting to establish WSS connection between WampSharp client & WampSharp router. I have an unsigned certificate.

Client code:

var cert = new X509Certificate2(@"path/to/cert", "password");
var binding = new JTokenMsgpackBinding();
var ws = new WebSocket(location);
ws.Security.AllowNameMismatchCertificate = true;
ws.Security.AllowUnstrustedCertificate = true;
ws.Security.Certificates.Add(cert);
IControlledWampConnection<JToken> connection = new WebSocket4NetBinaryConnection<JToken>(ws, binding);
IWampChannel channel = channelFactory.CreateChannel("Default", connection, binding);
channel.Open().Wait();

Router code:

Host = new DefaultWampHost(mConfig.ServerAddress, new X509Certificate2(mConfig.CertificateLocation, password));

I tried doing it in many other different ways but it always crashes here and "connection is closed before it can be established":

        /// <summary>
        /// Call this when a new connection is established.
        /// </summary>
        /// <param name="connection">The new connection.</param>
        protected void OnNewConnection(TConnection connection)
        {
            string protocol = GetSubProtocol(connection);

            ConnectionListener listener;

            if (mBindings.TryGetValue(protocol, out listener))
            {
                listener.OnNewConnection(connection);
            }
            else
            {
                mLogger.ErrorFormat("No handler registered for protocol '{Protocol}'",
                                    protocol);
            }
        }

GetSubProtocol returns null (in TextBinaryTransport.cs), see pic:

Any help would be appreciated.
Thank you

Hi Andrej,

In case that you create the underlying WebSocket yourself, you need to set up the subprotocol field yourself (in your case to wamp.v2.msgpack).

Instead, you could simply use fluent syntax api, and call SetSecurityOptions method.

Thanks a lot! Made it work using Fluent Syntax.

Here's the code (for future reference):

IWampChannel channel = factory.ConnectToRealm("Default")
    .WebSocketTransport(name => new WebSocket(location, "wamp.2.msgpack"))
    .SetSecurityOptions(o =>
    {
        o.Certificates.Add(new X509Certificate2(@"path/to/cert", "password"));
        o.AllowNameMismatchCertificate = true;
        o.AllowUnstrustedCertificate = true;
    })
    .MsgpackSerialization()
    .Build();

// This is also neccessary
ServicePointManager.ServerCertificateValidationCallback = (s, crt, chain, policy) => true;

channel.Open().Wait();

Also it's wamp.2.msgpack, not wamp.v2.msgpack

You can replace the line

    .WebSocketTransport(name => new WebSocket(location, "wamp.2.msgpack"))

with

    .WebSocketTransport(name => new WebSocket(location, name))

or even better

    .WebSocketTransport(location)
