我家裡有一台 WDMyCloud 伺服器，並啟用了 FTP。我有一個每日腳本在遠端伺服器上運行，透過 WinSCP 使用 FTP 來備份我的檔案（更改）。
我發現它可以工作幾週，然後停止工作，遠端服務顯示：
reconnecttime 120
confirm off
Connecting to MY_IP ...
Connection failed.
Timeout detected. (control connection)
Connection failed.
No session.
如果我連接到我的家庭伺服器並重新啟動它，它會再次工作，持續幾週。
我不知道如何解決這個問題，而不需要每次都重新啟動，這是不需要的。
運行netstat -s（如果此資訊有幫助）：
