After Update to DSM 6.2-23739 FTPS not working with Win 7 clients

Unread post by ruxton_bruce » Thu Jun 28, 2018 3:53 am

My DS1815+ updated itself to DSM 6.2-23739 the night before last and since the Update I have a problem with Windows 7 machines that upload to it using a command line FTPS SSL/TLS product called MoveIt Freely. All Windows 10 clients that upload using the same command line utility have no problems, it is only with Windows 7 clients (Connected remotely or on the Local LAN has exactly the same problem)

The error I receive on the Windows 7 clients is:-

C:\FTP>ftps -e:on
220 Synology FTP server ready.
234 AUTH TLS command successful.
> ftp: connect: Security handshake failed.
Security handshake failed.

I tried the Online help desk and they were no help except for suggesting that I use regular FTP instead of FTPS - which I do not want to do or Upgrading the PC's to Windows 10 - Which isn't an option.

Any help would be much appreciated.

Kind Regards
