problem in ftp- Could not read from socket: ECONNABORTED - Connection aborted

Hi

I use "Ubuntu 18.04.4 LTS (Bionic Beaver)) ISPConfig 3.1.15p3"
but I have a problem in ftp connect, here is the complete log from FileZilla:

Code:

I get the same error in active and passive FTP. I can connect the server only when I use (plain FTP) encryption.

any help please?

I tried to do the steps in this tutorial:
but I don't know the external IP, Or how can I get it.

 

the external ip is the public ip of the server/domain name you're trying to connect to. or a firewall/load-balancer in front of that server.
ping or nslookup of the fqdn should give you the public ip address.

 

thank you for your reply

I used FileZilla before with the same server and it worked fine (the control panel was VestaCP), but when I switched to Ispconfig 3 as a control panel I get this problem

 

problem is solved. Thank you Mr. Till
I use "Transmit" and it works fine.
Any suggestions about the best FTP client for macOS ?
