The error below confirms that a connection is possible, but was 
immediately closed again as soon as FullSync tried to log in...
There are two things I could think of:
  * Configuration problem: wrong username / password, unsupported login 
method,... the FullSync log file may contain further hints about this.
  * Unlikely but possible: Your hostname is a dynamic DNS based name, 
the Java runtime used by FullSync may cache name resolution results for 
a long time and your IP address might have changed since FullSync first 
tried to access it. Restarting FullSync might help in this case.

General Warning: FTP is horrible. Connecting an FTP server to the 
internet is a really bad idea. Switching to SFTP (not FTPS) and using 
Key-Based authentication is much better in terms of security, privacy 
and functionality.

If both options from above don't lead to anything then a network trace 
using Wireshark or a similar tool may be needed to figure out what the 
problem really is.
