Confirm host, port and credentials with Test connection. Check whether a firewall is blocking outbound FTP. Verify the server is FTP and not SFTP.
Login succeeds but the folder is empty
Check the remote path. Many servers place you in a home directory, so the path may need to be relative to that rather than absolute.
Files download every run despite not changing
The server's timestamps are probably unreliable. Set Compare by to Size only.
Changed files are not picked up
If the file is rewritten in place at the same size, size comparison won't see it. Set Compare by to Timestamp only or Size and timestamp.
Local files disappeared
Pruning is on and the remote listing succeeded but didn't include them — usually a wrong remote path. Turn pruning off, fix the path, and confirm with Test connection.
Nothing happens at the scheduled time
Confirm AUTO is on, the job's tick box is ticked, and the application is actually running. Closing to the tray keeps it running; quitting from the tray menu does not.
Transfers are slow or the connection drops
Downloads use one file at a time on a single connection by design. If a shared host is throttling, move the schedule outside peak hours.
A .part file is left behind
The run was interrupted before the transfer completed. It will be replaced on the next run — the partial file is never renamed into place.
