Applicable to:

Symptoms
- Passive FTP connection does not work after enabling Plesk Firewall Tools & Settings > Firewall > Enable

# ftp> dir

CONFIG_TEXT: proftpd: pam_listfile(proftpd:auth): Couldn't open /etc/ftpusers
proftpd[4513]: (203.0.113.2) - USER username: Login successful. - ip_conntrack_ftp module is not loaded:
# lsmod | grep conntrack_ftp
#
Cause
The described behavior is expected if ip_conntrack_ftp module is not loaded.
This is Plesk bug with ID # PPPM-6187: the notification in Plesk UI will be added in future Plesk updates.
Resolution
As a workaround, configure passive ports and load required module as described in the article How to configure a passive ports range for ProFTPd on a server behind a firewall
