When transferring files through FTP, I am getting alot of ‘connection refused’ errors, so I decided to test my FTP connection on ftptest.net, with the following result:
I used explicit FTP over TLS, am running latest version of virtualmin/webmin on Ubuntu 16.04.

Virtualmin/ubuntu comes with proftpd 1.3.5a pre-installed (proftpd -v) and after searching online it seems this is a known issue with this version:
Is it possible to update proftpd?
