FTPS Connection Error


i’m trying to get a Connection to a SFTP / FTPS Server which is provided by a Synology NAS-System.
I’m unable to get a connection working. I already tried every possible combination (Implicit / Excplicit; active / passiv). I receive the enclosed errors:


When i connect with an FTP Client like Filezilla, i will not have any problems to get a connection by ftps or sftp.

Any Ideas? :slight_smile:




When i try to get a connection by RebexFTPClient.exe i’m able to get a connection whith “FTP/SSL explicit” and “passive Mode”.

With the same settings i receive and error in sqlbackupandftp:

Permission denied
