How to check if my FTP/SFTP connection is working?

To verify that your FTP/SFTP connection is working, follow these steps:

1. Test the same credentials (host, username, password, port) in FileZilla. If FileZilla returns an error such as "Authentication failed" or "Please check username & password", the credentials are incorrect and must be confirmed with your supplier.

2. Confirm that the filename and folder path match exactly what exists on the FTP server. Filenames are case-sensitive (for example, CO0040StoCK.csv is different from CO0040Stock.csv).

3. Ensure the file actually exists on the server. If you receive errors like "ftp_file_not_found", compare the feed’s configured path with the actual server directory.

4. Once corrected, use the Test Connection button in Step 1 of Stock Sync to confirm the connection.

Additional checks:

• Make sure the host does not include http:// or folder paths. It should be only the server address (e.g., ftp.example.com or an IP).
• For FTP, the default port is usually 21, and some servers require setting encryption to Plain FTP.
• If your server uses firewall restrictions, ensure Stock Sync’s static IP 52.20.189.51 is whitelisted.
• Some servers require the exact filename, and dynamic or date-based filenames cannot be fetched unless the full filename is provided.
• If the connection times out even after whitelisting, ask the server owner to check their firewall or security settings.
• FTP access is disabled on the Free plan, so feeds depending on FTP will not work unless the plan includes Update Feed.
