403 only when cookies are used

We have an implementation of SignalR that is working perfectly fine with a Web application. When trying to use this with a native app:

class FHubConnection: SRHubConnection {
    static let shared = FHubConnection(username: "bob")
    private var hub: SRHubProxy!

    init(username: String) {
        super.init(URLString: APIRouter.baseURLString, queryString: ["username": username], useDefault: true)
        hub = createHubProxy("appHub") as! SRHubProxy
    }
}

FHubConnection.shared.start()

When we're not logged in (no cookie), we get:

However when we have a cookie in the request, we get the following:

What's notable is that the web app is working fine. The AppHub serverside does not Authenticate, so I don't know why we would be getting forbidden here.
