尝试连接到远程SFTP服务器时，读取全部时出现Paramiko EOF错误

Question

我正在尝试使用python连接到远程sftp服务器。此服务器由第三方拥有和管理

我可以使用Filezilla和Pycharm的部署工具连接到服务器（因此我认为可以排除防火墙和白名单问题）

我可以使用连接到演示服务器

import paramiko

transport = paramiko.Transport(('test.rebex.net',22))
transport.connect(username='demo',
                  password='password')
print(transport) 

输出：

<paramiko.Transport at 0xf448c50 (cipher aes128-ctr, 128 bits) (active; 0 open channel(s))>

但是，当尝试连接到我需要的服务器时，我会运行：

import paramiko

transport = paramiko.Transport((ftp_server,22))
transport.connect(username=username,password=password)

得到

Traceback (most recent call last):
  File "<input>", line 2, in <module>
  File "/venv/lib/python3.7/site-packages/paramiko/transport.py", line 1291, in connect
    self.start_client()
  File "/venv/lib/python3.7/site-packages/paramiko/transport.py", line 660, in start_client
    raise e
  File "/venv/lib/python3.7/site-packages/paramiko/transport.py", line 2055, in run
    ptype, m = self.packetizer.read_message()
  File "/venv/lib/python3.7/site-packages/paramiko/packet.py", line 459, in read_message
    header = self.read_all(self.__block_size_in, check_rekey=True)
  File "S/venv/lib/python3.7/site-packages/paramiko/packet.py", line 303, in read_all
    raise EOFError()
EOFError

我怀疑this问题是相关的，但我还是在调用connect()时得到了相同的错误

我还尝试使用SSHClient对象并对其调用connect（），但得到了相同的错误

我对网络或SSH&；的理论理解很少；SFTP所以，当packetizer试图读取报头以进行初始连接时，服务器似乎没有返回任何信息，但我不明白为什么会这样，或者如何解决。有人能解释这一点吗，或者甚至能给我指出一个帕拉米科的替代品（如果这可能有帮助的话）
