OSMC granted access for SFTP not for FTP

Team,
I can successfully access the Vero 4K box with SFTP but not with FTP.
I get the following message
Connection attempt failed with ECONNREFUSED - Connection refused by server
Why does that work with SFTP and not with FTP?

Is the FTP server installed and running?

Hi Sam,
by searching the forum, I realized I had to install the FTP server. I thought it was installed by default like the SFTP built-in.
I followed your earlier procedure (through Putty) and it is working now.
Thanks
