Question

我刚刚将MVC网络应用程序部署到我的Windows Server 2012.它安装了Windows 8和IIS v8。该应用程序使用SignalR，我想使用websockets，但它会出错。

在每个浏览器（chrome ff，ie）中，错误都是相同的：

"NetworkError: 500 Internal Server Error - https://domain.com/signalr/connect?transport=webSockets&connectionToken=wiiR333%2BkbKu0Ex2SPZLE9W9X6eAm5lBssbjXbqCvl0QpjAiGtHkn1xiIQHYGi3O4DDLIv7whTahVb8Ll5kfwjnrzaZaDYCApWj5aWm6d1cZzxH89K%2BouHziBH7dCt9I&connectionData=%5B%7B%22name%22%3A%22charthub%22%7D%5D&tid=8"

详细的错误消息是：

Exception information: 
    Exception type: InvalidOperationException 
    Exception message: Not a valid web socket request.
   at Microsoft.AspNet.SignalR.Transports.WebSocketTransport.AcceptWebSocketRequest(Func`2 callback)

   at System.Web.HttpApplication.AsyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

我在SignalR Jabbr聊天中询问了错误是什么，他们告诉我有什么东西阻止了连接。我查了一下，TCP端口80和端口443都在监听。

IIS信任级别为Full (internal)，我们未使用负载平衡。 Websockets protocol已安装。

可能出现什么问题？

Websocket SignalR无法启动
