I have one server, Linux based, I use for some years like a backup cloud server. This work very well with client like Windows 7, Ubuntu and Android. But Not with Windows 10.

All programs I have used for connections worked well without problems for years with these clients.

Now I would like to connect another computer for online backup with SyncBackFree or freefilesync on the Windows 10 Operating System and I have some problems with FTP connections.

To do a test, I also tried the FTP connection with FileZilla and even here, with Windows 10, I find the same problem.

The program I use as FTP server is vsftpd, but I have also tried ProFTPD, showing the same problem.

Here's some test:

The FTP server on a Linux system with ProFTPD (with vsftpd it is a very similar result)
