Major issue with ProFTPd

Below is the config code.....

# This is the ProFTPD configuration file
#
# See: http://www.proftpd.org/docs/directives/linked/by-name.html

# Security-Enhanced Linux (SELinux) Notes:
#
# In Fedora and Red Hat Enterprise Linux, ProFTPD runs confined by SELinux
# in order to mitigate the effects of an attacker taking advantage of an
# unpatched vulnerability and getting control of the ftp server. By default,
# ProFTPD cannot read or write most files on a system nor connect to many
# external network services, but these restrictions can be relaxed by
# setting SELinux booleans as follows:
#
# setsebool -P allow_ftpd_anon_write=1
# This allows the ftp daemon to write to files and directories labelled
# with the public_content_rw_t context type; the daemon would only have
# read access to these files normally. Files to be made available by ftp
# but not writeable should be labelled public_content_t.
#
# setsebool -P allow_ftpd_full_access=1
# This allows the ftp daemon to read and write all files on the system.
#
# setsebool -P allow_ftpd_use_cifs=1
# This allows the ftp daemon to read and write files on CIFS-mounted
# filesystems.
#
# setsebool -P allow_ftpd_use_nfs=1
# This allows the ftp daemon to read and write files on NFS-mounted
# filesystems.
#
# setsebool -P ftp_home_dir=1
# This allows the ftp daemon to read and write files in users' home
# directories.
#
# setsebool -P ftpd_connect_all_unreserved=1
# This setting is only available from Fedora 16/RHEL-7 onwards, and is
# necessary for active-mode ftp transfers to work reliably with non-Linux
# clients (see http://bugzilla.redhat.com/782177), which may choose to
# use port numbers outside the "ephemeral port" range of 32768-61000.
#
# setsebool -P ftpd_connect_db=1
# This setting allows the ftp daemon to connect to commonly-used database
# ports over the network, which is necessary if you are using a database
# back-end for user authentication, etc.
#
# setsebool -P ftpd_is_daemon=1
# This setting is available only in Fedora releases 4 to 6 and Red Hat
# Enterprise Linux 5. It should be set if ProFTPD is running in standalone
# mode, and unset if running in inetd mode.
#
# setsebool -P ftpd_disable_trans=1
# This setting is available only in Fedora releases 4 to 6 and Red Hat
# Enterprise Linux 5, and when set it removes the SELinux confinement of the
# ftp daemon. Needless to say, its use is not recommended.
#
# All of these booleans are unset by default.
#
# See also the "ftpd_selinux" manpage.
#
# Note that the "-P" option to setsebool makes the setting permanent, i.e.
# it will still be in effect after a reboot; without the "-P" option, the
# effect only lasts until the next reboot.
#
# Restrictions imposed by SELinux are on top of those imposed by ordinary
# file ownership and access permissions; in normal operation, the ftp daemon
# will not be able to read and/or write a file unless *all* of the ownership,
# permission and SELinux restrictions allow it.

# To prevent DoS attacks, set the maximum number of child processes

It was working before but stopped about 6 weeks ago. The below is what I get with the standard setup of FTP over TLS:

Status: Connection established, waiting for welcome message... Status: Insecure server, it does not support FTP over TLS. Status: Connected Status: Retrieving directory listing... Command: PWD Response: 257 "/" is the current directory Command: TYPE I Response: 200 Type set to I Command: PASV Response: 227 Entering Passive Mode (71,43,85,106,185,7). Command: MLSD Error: Connection timed out Error: Failed to retrieve directory listing

I found out the issue. It's Centos 7.... I ran the following commands and the FTP over TLS plus the passive worked. It had to do with the update to centos 7 from centos 6

firewall-cmd --permanent --add-port=40000-50000/tcp

firewall-cmd --reload
