Invalid IP/Domain for the ftp connection??

[Sentinal]

Hello, I've got this problem.

I want to use "Manage User Backups" in my reseller and make a backup from all my users to my home server using a different port (not port 21). But when I try to use another port I get this error.

Error during Cron Modification

Details
Invalid IP/Domain for the ftp connection

What I fill out as ftp server info is:

IP: 00.00.00.00:port
Username: unameexample
Password: pwdexample
Remote Path: ftppath

What is it what I do wrong? Or is there another solution?

You probably need to modify the script that actually does the uploading.
ftp_upload.php
