FTP error usually looks like this:
The data connection cannot be established: ECONNREFUSED – Connection refused by the server.
systemd 111
netstat -natp| grep :111
tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN 1/systemd
To 111 port listening disable you can like this:
systemctl stop rpcbind.socket
systemctl disable rpcbind.socket
