Quick answer
For Interactive Online, use sftp:// before the assigned hosting server in Quickconnect and enter its assigned SSH port. For an individual private-key file, use FileZilla Site Manager. Leaving the port blank can select the wrong default.
Applies to
For FileZilla Client on your own computer and an authorized Interactive Online hosting login. Our file-transfer workflow uses SFTP over SSH; FTP access is retired. Select SFTP, use the assigned server and SSH port, and authenticate as the eligible cPanel account with an authorized key. Legacy FTP-only subaccounts cannot sign in to SFTP. Check the connection guide for your server and port.
Steps
- Obtain the exact authorized hostname, username, protocol and port. For SFTP, use sftp:// with the hostname and the assigned SSH port.
- Use the authorized cPanel account identity and a supported local key/agent setup, then choose Quickconnect. If you need to select a key file for this connection, use Site Manager instead. Verify any first-connection host-key fingerprint through a trusted service source before accepting it.
- Confirm the remote account/folder before a transfer. Use Site Manager for a repeatable saved setup and disconnect when finished.
Check the result
List the intended remote folder and perform a harmless upload/download comparison in an authorized test folder.
Troubleshooting and support
For a host-key change, stop and verify it with support. Do not blindly accept a new key or switch to plain FTP to bypass an error.
If the problem continues, contact support from the account that owns the service. Include the domain, exact error, time and time zone, tool name, and a redacted screenshot. Keep passwords, private keys, cookies and private message content out of the ticket.
