我正在尝试使用 Python 连接到 FTP，ftplib但它显示连接成功，但每次我运行任何服务器命令时，它都会以TimeoutError. NOOP命令显示200 NOOP ok.响应，但是当我尝试ftp.dir()或任何服务器命令时，它失败并出现以下错误。

我也试过了ftplib.FTP()，显示同样的错误。
ftplib与其他非 SSL 服务器一起工作正常。- 远程服务器正在运行
Ubuntu 18.04.4 LTS。vsftpd FTP用户是用vestacp.- 我通过更改
/etc/passwd文件更改了用户的家庭住址。 - 一切正常，
FileZilla没有来自同一本地服务器的任何延迟。
这是vestacp vsftpd配置：
