我使用 FileZilla ftp 客户端很多年了。当前版本是 3.43.0 问题是使用版本 3.XX 时，我无法使用 vsFTPd 2.0.7 服务器连接到我的一个存储 -> netgear stora（从路由器打开了被动端口）。我收到的错误是：
Status: Resolving address of MY-IP
Status: Connecting to MY-IP:2121...
Status: Connection established, waiting for welcome message...
Response: 220 (vsFTPd 2.0.7)
Command: USER XXX
Response: 331 Please specify the password.

从同一台计算机，我可以使用以下方式进行连接：Windows FTP 客户端、WinSCP、甚至 FileZilla v2。

在 FileZilla3 选项中，我将“加密”选项卡设置为仅使用普通 FTP（不安全）
我不确定，但几周前它还能正常工作。没有做任何更改 - FTP 服务器、路由器设置。还尝试将 FileZilla 版本降级到之前的几个版本，但没有成功。有什么想法吗？
提前致谢 ！

我想我找到了解决方案。FileZilla v.3 客户端 -> 设置 -> 连接 -> 将超时时间增加到 30-35 秒。我不知道为什么服务器变得……更慢了。
