paramiko.ssh_exception.SSHException: Incompatible ssh server (no acceptable ciphers)

[ghostzero192]

hi i'm using paramiko 2.7.2 on windows 10 for connecting to a sftp site the following code has been working just fine (even as a service) and suddenly it just stopped working here is the error i'm getting

Traceback (most recent call last): File "C:\Users\Administrator\Documents\Pax\otra\par.py", line 14, in <module> transport.connect(None,username,password) File "C:\Program Files\Python37\lib\site-packages\paramiko\transport.py", line 1294, in connect self.start_client() File "C:\Program Files\Python37\lib\site-packages\paramiko\transport.py", line 663, in start_client raise e File "C:\Program Files\Python37\lib\site-packages\paramiko\transport.py", line 2086, in run self._handler_table[ptype](self, m) File "C:\Program Files\Python37\lib\site-packages\paramiko\transport.py", line 2201, in _negotiate_keys self._parse_kex_init(m) File "C:\Program Files\Python37\lib\site-packages\paramiko\transport.py", line 2418, in _parse_kex_init "Incompatible ssh server (no acceptable ciphers)" paramiko.ssh_exception.SSHException: Incompatible ssh server (no acceptable ciphers)

and here is the code:

import paramiko
from paramiko import SFTPClient
import os
import csv

host,port = "sftpaddress",22
transport = paramiko.Transport((host,port))

username,password = "username","pasword"
transport.connect(None,username,password)

sftp : SFTPClient = paramiko.SFTPClient.from_transport(transport)

ftpFiles = sftp.listdir('/')
print(len(ftpFiles))
if sftp: sftp.close()
if transport: transport.close()
also i'm able to connect using winscp client, no problem

i even added the 'arcfour' ones just to try and nothing
forgive my english and noobnes
