hi,
i add remote ftp backup details successfully with custom ftp port 821. but, after create backup with command line get error
ftp: connect to address ::1: Connection refused
successfully connect if try with php ftp login.

<?php
// connect to FTP server
$ftp_server = "localhost";
$port = "821";
$ftp_username = "abc";
$ftp_userpass = "123";

$ftp_conn = ftp_connect($ftp_server, $port) or die("Could not connect to $ftp_server");

// login
if (@ftp_login($ftp_conn, $ftp_username, $ftp_userpass))
  {
  echo "Connection established.";
  }
else
  {
  echo "Couldn't establish a connection.";
  }

// close connection
ftp_close($ftp_conn);
?>

why get this error?

  • localhost:821 is cloudflared remote host tunnel.

Try manualy to connect using ftp cli, nothing hestia can resolve.

Check if port 821 is open in the firewall and ftp is listing to that port

Probally this is not the case…

Also localhost means 127.0.0.1 and does not go trough Cloudflare…

yes after use 127.0.0.1 work fine with sftp port 22.
but, not work with ftp port 21. ask for password and login success… but, stuck at “Retrieving directory listing”…
i know this is not hestiacp problem. but your small help save my time.
thank you @Raphael and @eris :heart:
