SmartFTP cannot connect server while other client can.

Hi,
im using SmartFTP for some years, and never had problems with the server ftp://img.rallyonline.pl. It is the FTP server of our website, and you need login and pass, but i think for the solution (if existing) of this problem you would not need user and pass.
The problem is that newest version of SmartFTP and some older versions cannot connect to this server. In the past there were no problems with this server. Other servers work still perfect in SmartFTP. SmartFTP throws:
[19:58:45]     SmartFTP v1.5.988.25



[19:58:45]     Resolving host name "img.rallyonline.pl"



[19:58:45]     Connecting to 217.160.254.220 Port: 21



[19:58:45]     Connected to img.rallyonline.pl.



[19:59:05]     Timeout (20s).



[19:59:05]     Active Help: https://www.smartftp.com/support/kb/45



[19:59:05]     Client closed the connection.



[19:59:05]     Cannot login waiting to retry (30s)...
The problem is very strange for me, because this server replies to ping and works without problems in other clients, like FTPCommander.
Doesnt matter if Sygate Firewall is on or off. Im also behind a router, the USR 9105.
Any ideas? I have no more Please help
