不一致的ASP.NET WebHooks

我想設置一個Azure WebJob來使用自定義WebHook將數據推送到Web應用程序（然後將它推送到使用SignalR的客戶端）。 WebJob按計劃運行（它輪詢另一個服務以檢查是否有任何新數據）。不一致的ASP.NET WebHooks

我已經基於此MSDN blog post，以及CustomSender.WebJob和CustomReceiver來自MS的示例項目。

該系統在Azure上運行，並且大多數都能正常工作，但並不一致。這項工作每三分鐘運行，並始終將網絡掛接 - 至少它總是記錄此跟蹤消息，我認爲意味着它發送網絡掛接：

Configuring 'DataflowWebHookSender' with a total of 3 attempt(s) of sending WebHooks.

然而WebHookHandler並不總是收到網絡掛接。有時候，我得到下面的跟蹤消息，有時什麼也沒有：

Processing incoming WebHook request with receiver 'custom' and id ''.

雖然有明顯好幾個地方，有可能是一個問題，即間歇工作的事實讓我覺得，代碼和配置都行，而且我對於處理程序爲什麼沒有更一致地接收WebHooks有點困惑。期望WebHooks始終工作我錯了嗎？
