| Problem | Checks and corrective action |
|---|---|
| Cannot connect at all | 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. |
| FTPS fails with a handshake or TLS error | Some servers require TLS session resumption between the control and data connections, which isn't supported. See Known limitations. Use plain FTP on a trusted network, or different tooling. |
| FTPS unavailable and the title bar says "(no TLS support)" | The OpenSSL libraries aren't present alongside the application. Plain FTP still works. |
| 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. |
Information to collect before asking for help
- BroadcastSync version and Windows version.
- Whether plain FTP or explicit FTPS is in use.
- The exact error text from the status panel or log.
- Whether Test connection succeeds.
- The transfer mode and comparison rule for the affected job.
