Signalr - websocket successfully connected but client events only called with long pooling

问题

I'm using windows server 2012 and activated websockets on it. When signalr use websockets, the connection is successfully started but no event in client side are called, only if I force signalr to connect with long polling....

Any suggestion ? Thanks
