I’ve just starting using Duplicati today and am really impressed. I’ve set up a few different destinations but cannot get FTP to work. After putting in the settings (FTP, ✓ use SSL), and pressing ‘Test connection’, I instantly get this error: “Failed to connect: The remote certificate is invalid according to the validation procedure.” It doesn’t try to connect and wait a bit, it is almost instant after pressing the button.
I’ve tried pressing “Test Connection” while the live log (profiling log level) is running, but nothing is displayed.
The FTP account I’m using was generated by a shared hosting cPanel. I’ve entered ftp.example.com, port 21, with no advanced options checked.
