This is a simple walk through to set up your ftp on the NextCloud you have just installed.
If you wish to use Ftp and not sftp then you will use port 5757 if the fpt is a QuickBox setup.

when it is working you will see the green circle
then you can move over to your files and you should see the ftp/sftp
