您好我正在使用pyftpsync来上传新图像（每天下载），跳过现有的图像。
从作者网站我正在使用此代码（当然还有我的个人数据）：
from ftpsync.targets import FsTarget
from ftpsync.ftp_target import FtpTarget
from ftpsync.synchronizers import UploadSynchronizer
local = FsTarget("~/temp")
user ="joe"
passwd = "secret"
remote = FtpTarget("/temp", "example.com", username=user, password=passwd)
opts= {"force": False, "delete_unmatched": True, "verbose": 3, "dry_run" : False}
s = UploadSynchronizer(local, remote, opts,tls=True)
s.run()
只有在我删除tls选项时才能正确地为我工作，否则在连接到我的服务器时会出现此错误：
Traceback (most recent call last):

这显然是与加密有关的问题，但我不知道如何修复它。
