Pi not accepting file transfers to Kodi

I want to transfer some VPN certificate files from my Mac OS 10.12.4 laptop to Kodi on my Raspberry Pi B+.

The Pi OS is LibreElec 8.0.1 running Kodi 17.1

The Pi has a wireless dongle.

The FTP I’m using is Filezilla 3.25.2

I’m using the IP address from Kodi>System>System information as the Host address

The Protocol selected in Filezilla is SFTP

User: root

Password: libreelec

Port: 22

But I get the following status messages from Filezilla:

Response: fzSftp started, protocol_version=8
Command: open “[email protected]” 22
Error: Connection refused
Error: Could not connect to server

What am I doing wrong?

Is there something in Kodi that I need to turn on, turn off, defeat, that will allow the connection to successfully proceed.

Grateful to receive the help and guidance from forum members.

Many thanks.
