File copy errors and connection drops with FTP server

Greetings.
My FTP server is giving me a problem when I try to put files in it.
It gives me this error message when it gets up to 99% then for some reason the connection drops.
"Detected Timeout. Remote side failed in Copying files. Opening BINARY mode data connection for "file name here"".
Every file that I try to put on it happens. If anyone has a solution to this,
I would like to know.
