I have a simple script to connect into a FTP server:
from ftplib import FTP
# Here is fine
ftp = FTP(host='')
ftp.login(user='', passwd='')
ftp.cwd('/test/')
# Here I got the error
ftp.nlst()
The connection it is just fine, the error is happening every time that I try to use commands to list the FTP directory, such as nlst, dir or even retrlines('LIST'):
230 Login successful.
250 Directory successfully changed.
Traceback (most recent call last):
File "scripts/test.py", line 6, in <module>
print(a.nlst())
File "/usr/lib/python3.5/ftplib.py", line 558, in nlst

raise err
File "/usr/lib/python3.5/socket.py", line 703, in create_connection
sock.connect(sa)
ConnectionRefusedError: [Errno 111] Connection refused
I already tested the connection with FileZilla and it is working fine, this error just happens when I try to list the directory with python. If I try to retrieve files or create directories through python it will work, only the "list" commands that gives the problem.
Environment: I'm using debian 9 with python3.5
I already reinstalled both pythons (2 and 3) in my machine but didn't worked. Also, I tested the same script in a Linux Mint that I have and it is working fine. Could someone know what this could be? Thanks.
[EDIT]
This is the FileZilla log (debug mode) when I connect to the same FTP server:

Just reminding that the code is working fine in another machines, the problem is happening only in Debian when I try to list any directory in the FTP.
Thanks!
