It was this option. As mentioned, we have the same configuration across other servers and we have no issues.

# Enable ftp helper via the iptables CT target on supporting kernels (v2.6.34+)
# Enable ftp helper via the iptables CT target on supporting kernels (v2.6.34+)
# instead of the current method via /proc/sys/net/netfilter/nf_conntrack_helper
# This will also remove the RELATED target from the global state iptables rule
#
# This is not needed (and will be ignored) if LF_SPI/IPV6_SPI is disabled or
# the raw tables do not exist. The USE_CONNTRACK option should be enabled
#
# To enable this option, set it to your FTP server listening port number
# (normally 21), do NOT set it to "1"
USE_FTPHELPER = "0"

Thank you.
I had a check and this is set to 0 by default on all our servers,

we started having this problem on one of our servers.
When changing USE_FTPHELPER = "0" para "21" the problem has been fixed.

On the other servers we have, the USE_FTPHELPER = "0" works normally.
