You are using FTP active mode with Filezilla, while passive mode with WinSCP:

So how could you tell filezilla was active mode? Oh and I changes WINSCP to use active mode (-passive=off) and it worked.

Thanks

In the log, you can see Filezilla is using PORT command (active mode), while WinSCP was using PASV command (passive mode).
