Hello, I can only connect via sFTP to my server. That was not a problem until now because I need to give access to FTP to someone (for support).
I created a new user for FTP only but when I connect via FTP i get this:
Error: Failed to retrieve directory listing.
I already tried this https://www.virtualmin.com/documentation/web/faq#FTP_Service_isn-t_working
By they way, I have Ubuntu Linux 16.04.1 and Virtualmin 6.02. And proftpd-basic 1.3.5a-1build1
