WSError(type: Starscream.ErrorType.protocolError, message: "", code: 1000)

I got this error code when I was using websocket transport and I don't know why. When I had used servertransport it worked.

Facing the same problem, seems my SignalR server is expecting clientProtocol=1.5 during connection, so I have set the version to 1.5 in my own HubConnection, and add the clientProtocol param in WebSocketTransport
