[syrakozz]

is it a server site or client issue ?

[joeldart]

somethign that just stood out to me is the negotiate goign over websockets. What client code are you using to connect?

[syrakozz]

im using DyKnow/SignalR-ObjC

[syrakozz]

and i tried with auto and with websocket

[joeldart]

I mean, the objective c code. Your connection to the server, firewalls, whether you use https, etc will largely dictate whether a websockets connection is stable or if it has to fall back to a different transport. What I'm surprised by is that in my usage, the negotiate never goes over websocket as one of the concerns of negotiate is to figure out whether you can use websockets

Here's an example (from the readme) of what code I was asking about

// Connect to the service
SRHubConnection *hubConnection = [SRHubConnection connectionWithURLString:@"http://localhost/mysite"];
// Create a proxy to the chat service
SRHubProxy *chat = [hubConnection createHubProxy:@"chat"];
[chat on:@"addMessage" perform:self selector:@selector(addMessage:)];

Even i am facing the same issue. Is there any solution to resolve this error?
