python ftplib login OK but ftp.retrlines KO

Question

I try this python code with python 3.11.4 :

f = FTP(ftp_host)
print(f.login(ftp_login, ftp_password))
print(f.pwd())
f.retrlines('LIST')
f.close()

f.login, return :

230 Login successful.

f.pwd() return:

/home/ftp_login

But f.retrlines('LIST') doesn't works

Exception has occurred: TimeoutError [WinError 10060] Une tentative de connexion a échoué car le parti connecté n’a pas répondu convenablement au-delà d’une certaine durée ou une connexion établie a échoué car l’hôte de connexion n’a pas répondu

I have the same error using

f.nlst('/home/{}'.format(ftp_login)

I specify that the server to which I am trying to connect is a CentOS7 VM of which I am the administrator and I have just installed the vsftpd service then launched like this

sudo systemctl restart vsftpd

I have tried, to do the same things with CLI, from the same computer:

C:\Users\ME>ftp 192.168.0.103
