VM 的 RecoverPoint 和 RecoverPoint：連線叢集失敗，並顯示錯誤「連線叢集失敗」

嘗試將新的 RP 叢集新增至運作中系統。

連線叢集失敗，並顯示錯誤「連線叢集失敗。無法到達遠端 vRPA 叢集 （IP xxx.xxx.xxx.xxx）。
此錯誤出現在 WDM/Deployment Manager 和dm.log中：

雖然錯誤指向有問題的特定 IP （RPA1 的 WAN IP），但問題與不同的 IP
當系統新增站點時，必須使用叢集憑證更新所有新的 RPA。
當系統無法更新任何 RPA 上的憑證時，就會出現錯誤，在上述案例中為 Kbox 3 或 RPA 4。

主意：
識別在更新其憑證時發生問題的 RPA，在此情況下：

2019-05-10 15:05:21,353 [DistributeClusterCertificatesWorker_collection_0xYYYYYYYYYYYYYYYY-3] (CommandWorkerListener.java:58) INFO  - workers remaining: 0
2019-05-10 15:05:21,353 [CommandWorker-3] (AddSiteCommand.java:882) WARN  - Failed to distribute certificate.

這是新叢集的 Kbox 3 = RPA 4。

檢查原始叢集的 Site Control RPA 是否發生與此特定 RPA 的連線問題，解決這些問題，然後重試新增叢集作業。
