我建立了一個 FTP 網站。我將匿名訪問設為 true，並啟用了匿名身份驗證。
我使用伺服器上的 Windows 資源管理器對其進行了檢查，並且可以使用以下位址查看我的目錄清單：
ftp://host:port/
ftp://ip:port/
但是，我在 FileZilla 中看不到 FTP 的內容。這是日誌：
Status: Resolving address of DOMAIN
Status: Connecting to IP:PORT...
Status: Connection established, waiting for welcome message...
Status: Insecure server, it does not support FTP over TLS.
Status: Logged in
Status: Retrieving directory listing...
Command: PWD
Response: 257 "/" is current directory.
Command: TYPE I
Response: 200 Type set to I.
Command: PASV
Response: 227 Entering Passive Mode (...).
Command: LIST
Response: 150 Opening BINARY mode data connection.
Error: Connection timed out after 20 seconds of inactivity
Error: Failed to retrieve directory listing
Status: Disconnected from server
Status: Resolving address of DOMAIN
Status: Connecting to IP:PORT...
Status: Connection established, waiting for welcome message...
Status: Insecure server, it does not support FTP over TLS.

Command: PASV
Response: 227 Entering Passive Mode (...).
Command: LIST
Response: 150 Opening BINARY mode data connection.
Error: Connection timed out after 20 seconds of inactivity
Error: Failed to retrieve directory listing
我被困在這一點上。怎麼了？
我使用 Windows Server 2012 R2 和 IIS 8。
更新：這是 FileZilla 在活動模式的日誌：

答案1
看起來您正在嘗試以被動模式使用 FileZilla，但您的伺服器可能不支援它或透過防火牆阻止連接埠存取。由於您可以在活動模式下使用瀏覽器存取文件，因此請將 FileZilla 設為活動模式並重試。
