SFTP

SFTP gives you a fast, resumable connection for big transfers — uploading a modpack, downloading a world, syncing with an external editor. Open the SFTP tab on your server to find your connection details.

Connect

1. Open your server’s SFTP tab and copy the host, port, username, and password.
2. In your SFTP client (FileZilla, WinSCP, Cyberduck):
   • Protocol: SFTP (not plain FTP — Catalyst does not offer insecure FTP).
   • Paste the host, port, username, and password exactly.
3. You land in your server’s root directory, same files as the Files tab.

Good practice

• Stop the server before uploading or replacing world data or databases.
• Uploads go through the same permission checks as the file manager: you can only touch your own server.
• If your client warns about an unknown host key on first connect, verify the fingerprint with your administrator before accepting it.

Troubleshooting

• Authentication failed: credentials rotate — copy them fresh from the SFTP tab instead of reusing a saved password.
• Connection refused/timed out: the node may block the SFTP port, or your network may block outbound SSH. See networking issues.
• Transfers stall on huge folders: archive them first (zip), upload one file, then extract via the Files tab.
