SFTP and FTPS (FTP-SSL) are different protocols.
- SFTP = file transfer over SSH (usually port 22).
- FTPS / FTP-SSL = FTP with TLS encryption (usually port 21).
On GARMTECH shared hosting, website file uploads are supported via FTP-SSL (FTPS) and via Plesk File Manager. If your application, IDE, or “SFTP plugin” only supports SFTP, you will not be able to connect to shared hosting using SFTP.
What to use instead
- FTP-SSL (FTPS) — supported upload method for hosting files. Use your server hostname as the host to get a valid SSL certificate during the FTP connection.
- Plesk File Manager — upload files (or a ZIP archive) directly in Plesk under Files.
- Git deployment — if you deploy from a Git repository, you can push changes and deploy through Plesk.
How to avoid the most common mistake
If you see errors like “SFTP connection failed” or “Connection refused on port 22”, switch your tool to FTPS (Explicit FTP over TLS) and use:
- Host: your server hostname (example
s###.garmtech.com)
- Port: 21
