Python ftplib.error_temp 421 Timeout, looking for the best way to treat it

Question

First thank you for reading this.

My problem is that I kinda got behind the error by making an infinit loop

"while True" then I try my commands, Navigating, listing ...

I made an excepting to get me past this error 421 but am not satisfied.

Here is what I did :

          except ftplib.error_temp  as e:
                print('Time run out reconnect: ',e)
                RemoteTar.ftp_connect_to_site()

This exception will be printed it still true

so It going to stay stuck in that part of the code

what I did is desprately calling my function from a class this function is what allows me to reconnect

what I want is a better way to stay connected to the ftp server.

Thanks in advance

This kind of FTP error is generating by server. As usual FTP server drops connection if there are no any downloads/uploads of files.

You may try avoid this error by sending PASV command to FTP server (it helped me when I used FileZilla Server) after each command at server.

ftp.sendcmd('PASV')
