Hello,
I don't know anything about commons-net ftp, but the cause for this
behaviour is in the log you've sent:
PORT 172,22,69,22,193,11
200 PORT command successful.
LIST FILE_NAME
550 Cannot connect to {IP_ADDRESS} - timed out.
Your windows has a firewall activated which is blocking the incoming
data connection. You need to use PASV instead of PORT (sure there is a
way to configure commons-net to use passive mode) or disable your
firewall.
hth,
regards,
christian
