Hi,
a website I use to store pictures has switched from sftp upload to ftps. Before everything worked with SyncBack Pro.
Username and password are correct, DevArt, Port 21, Advanced > Encrypt the communication channel & Encrypt the data channel are enabled. When I test the connection I get the following error message: Internat Error: FTP Connect: FTP client not connected.

I also use the same setting within Lightroom and cyberduck (only username, passwort and port 21 required) and it works perfectly fine. Any ideas what i can do to get the connection within Syncback Pro?
Thank you.
