SignalR: Error during negotiation request: undefined

Question

I\'ve been trying to get a javascript signal-r client working against a self-hosted owin server. And am running into this issue. I\'ve tried both proxies and no proxy meth

Answer 1

If you are using SignalR 1.0.0 (which you should since it is now officially released), you need to change your call to MapHubs to enable cross-domain requests. This is assuming your website is not being served from localhost:9000. I'm guessing it isn't since you are passing in the url to $.hubConnection.

app.MapHubs(new HubConfiguration { EnableCrossDomain = true });

Before the final release of 1.0.0, CORS was enabled by default.
