Unable to Upload Large Files Using SSIS FTP Connection Manager

I am Unable to Upload a large File Using SSIS FTP Connection Manager, the file size is 1.21 GB, What do I need to do?, Is there a settings I need to change or increase.

I set the Time-out to 300 seconds, Retries to 6,  use passive mode unchecked and Chunck size set  to 1000 in the  FTP Connection Manager editor.

The FTP Task success with no warming or error message, but the large file was not downloaded (FTP), I am able to download small files with the same file format from the same ftp location and same ftp connection.

Please help !!!!

Regards

Mick
