Could it be some kind of proxy at the clients end ?

This is what the server gives me when I manually login, which I'm assuming is the FTP software
220 ProFTPD 1.3.3a Server (My FTP server)

I've just tried connecting without using passivemode on my PC and I don't get a rejection as you can see from the logs below. Unfortunately as this is part of my auto-update code, the FTP server's address is hard-coded in to the app, but if I need to I could compile a special build that logs on to your server - thanks for the offer of that.

Unusual to see an FTP server specifically refuse non-passive connections, do
you know what make?
