FTP backup error

[TaskSoftware]

Im trying to do a backup of a vhost to an external FTP server, but im getting an error.
I used the following command:

pleskbackup.exe --domains-name "domain.com" --ftp-server server.com --ftp-login ftpuser --ftp-password pass --ftp-passive-mode --only-hosting -v

The error Im getting (extracted from psadump.log):

Nevermind, it worked.
