"Cannot connect to ftp server" errors can often caused by firewall, Internet connection, or a security setting. Try to check if the IP you want to connect is up and running. You can do this from the RUN window: Start > RUN > ping IP. If you receive a reply, it means the IP is up. Alternatively, you may not have necessary access to connect to the servers. The simple way is to contact the developer of the application that uses the FTP servers to obtain more information.
