Use explicit FTP over TLS via http proxy with python ( FTP_TLS )

Question

I want to connect to an external server using explicit FTP over TLS using http proxy (with authentification)

I want to use a python function (3.6)

I test the connexion with FileZilla and it works.

I found that we can use the FTP_TLS function (https://docs.python.org/3/library/ftplib.html#ftp-tls-objects). I'am not able to set this function correctly.

The code I'am testing:

from ftplib import \*


\-- host settings


ftpusername = 'FtpUserName'


ftppassword = 'ftpPassWord'


ftp_host = 'xxxx.yyyy.fr'

\-- proxy settings


host_proxy = 'http.xxxxx.xxxxx.com'
(I test it also with the ip adress of the proxy: 1a2.21.aa.aa)


user_proxy = 'userNameProxy'


pass_proxy = 'passProxy'

u = "%s@%s %s" % (ftpusername , ftp_host, ftppassword)

ftp = FTP_TLS()

ftp.connect(host_proxy, 80)


ftp.login(u, user_pass, pass_proxy)
 

ftp.close()


ftp.quit()

The error I got:
