我已經在 osX 伺服器上啟用了快取伺服器，因為它亮了綠燈。在這個階段，我從應用程式商店下載了一個應用程序，但快取告訴下圖中沒有。在此 osX 伺服器上還需要設定其他內容嗎？
/Library/Server/Caching/Logs/Debug.log 中的日誌顯示：

在伺服器日誌中我可以看到：
Dec 8 11:27:40 MyOSXServer AssetCache[94461]: Caching Server started
Dec 8 11:27:40 MyOSXServer AssetCache[94461]: CoreData: Failed to load optimized model at path '/Applications/Server.app/Contents/ServerRoot/usr/libexec/AssetCache/AssetCache.momd/AssetCache-v5.omo'

應用程式商店要求更新server.appon EL Capitan，我更新了它，但到目前為止沒有任何反應。我在Log部分收到以下錯誤：
'/Applications/Server.app/Contents/ServerRoot/usr/libexec/AssetCache/AssetCache.momd/AssetCache-v5.omo'
XServer AssetCache[94461]: Registration succeeded. Resuming server.
在 osX 伺服器上，防火牆設定為關閉。我也應該在外部 Firefall（公用 IP 位址）上開啟此連接埠嗎？
