FTP Backups failing

[jhankins]

Greetings,

I'm runing 7.5.3 and am having a problem backuping up to my ftp server. I've verified I can login with a regular client from the server and put files up with no issue. It fails from plesk however.

This is the error I get
Unable to create the backup file: Error domain_bu execution: Can not upload backup file to FTP server.

A connection attempt failed because the connected party did not properly respond after a period of time, or established connnection failed because connected host has failed to respond.

---
Any help appreciated.

Actually Plesk 7.5.3 and 7.5.4 can't upload backup files to ftp in passive mode. So if port 20 closed somewhere then upload will fails.

Actually, it would be port 21.

actually

Active FTP :
command : client >1024 -> server 21
data : client >1024 <- server 20

so it's the inbound connection attempt fromthe server to the client's responded data port N+1 which will be some port greater than 1024. I tried turning off my Windows firewall and test but same result. Perhaps another firewall exists between that is blocking outbound.

Passive FTP :
command : client >1024 -> server 21
data : client >1024 -> server >1024
