My problem is that my FTP work great, exept when i upload files on a particular client server!

on this server happen that some files are uploaded fine and others not, they stop while uploading at half of it's size, then this error is displayed:

530 Sorry, the maximum number of clients (4) from your host are already connected. Unable to make a connection. Please try again.

Obviously this is not true, i'm the only one that is uploading!

Anyone had the same experience with this!?

PS: i have tried many different FTP, all display the same error or just hung up!

Thank's

Some FTP clients open up a connection for transfer and a control connection. That would tie up a minimum of two connections. Many FTP clients will open up multiple connections during file transfer to speed things up -- uploading 10 files through separate connections at the same time rather than uploading one at a time.

I've also seen this behavior with Windows 7 and servers using more recent versions of pure-ftpd. Connections on the server side never seem to close with Windows 7/pure-ftpd which leaves a number of them hanging until they time out.

For Linux server; Connect to root files (ex: WinSCP program)

file edit: root/etc/proftpd.conf
Update and Restart Services > Ftp Server

It could be a problem with that server, or because you're using a proxy server, or because you're behind NAT.

I got this error when I reached my disk space quota on a shared server. Deleting unnecessary files solved the issue.
