Download files with SFTP

Hi,

I've set up a SFTP server from where I want to download files with the FileMgr in StageNow. But when I try to download the files I get a "Server Reply: Protocol mismatch" error. When I put the same files on a "normal" FTP server, it works fine.

I've tried to connect to the server with FileZilla, and with just the username and password I can connect to the SFTP server, no need to install a certificate.

The url's I've used look like the following:

ftp-p://<username>:<password>@<url>:22/<file>

ftp-p://<username>:<password>@<url>:22/<file>?protocol=SSL

ftp-a://<username>:<password>@<url>:22/<file>

ftp-a://<username>:<password>@<url>:22/<file>?protocol=SSL

Has anybody an idea how to download files from a secure ftp server?
