NextCloud as FTP/FTPS/sFTP server

Can you tell me if we can use NextCloud as a FTP/FTPS/sFTP server?
I try to connect to the demo instance with FileZilla, but I can’t.
Best regards,

For what I know Nextcloud doesn’t offer a FTP server. But you could install one of many FTP servers, and access the Folder of the FTP server as external Storeage. Thats what I’m doing for sFTP.

FTP is not supported by Nextcloud, so Filezilla won’t help you. You could use Cyberduck and connect using Webdav directly to your Nextcloud instance.
