Python 3 ftplib提供OSError：[Errno 0]尝试使用storbinary（）函数上传文件时出错

Question

我正在尝试使用Python中的ftplib将文件上传到我的FTP服务器。 我收到错误OSError: [Errno 0] Error尝试从ftplib上传具有storbinary（）函数的文件时出错。 它可以与任何其他客户端一起使用（与FileZilla Client和WinSCP一起尝试）。

这是我的代码（ args只是一个包含来自argparse模块的参数的名称空间）：

ftp = FTP_TLS()
ftp.connect(args.host, args.port)
ftp.set_pasv(True)
ftp.login(user=args.user, passwd=args.password)

ftp.prot_p()

with open('COM.e', 'rb') as f:
    ftp.storbinary('STOR /commands/COM.e', f)

ftp.quit()

我收到此错误：

如果有帮助，这是服务器的输出（FileZilla，使用通过TLS的显式FTP）：

我究竟做错了什么？ 谢谢。
