使用pysftp的EOFError

如何解决使用pysftp的EOFError

我正在使用以下代码

host='xxx.xxxxxxxx.xxx'
username='xxxx'
password='xxxx'
port=5022
cnopts = pysftp.CnOpts()
cnopts.hostkeys = None
with pysftp.Connection(host=host,username=username,password=password,port=port,cnopts=cnopts) as sftp:
    print("hello")
    s=sftp.listdir()
    print(s)
    sftp.close()

它打印 hello 并且连接成功。但是 sftp.listdir() 给出了 EOFError。直接使用 Paramiko 也会出现同样的错误如果使用不带 () 的 s=sftp.listdir 给出下面的打印 s:

我可以连接 Filezila 并获取列表。以下是日志：
