FTP failed to start due to lack of TLS RSA Certificate - GUI not informative
When FTP fails to start due to the lack of a generated TLS certificate, it simply states that the service failed to start. /var/log/messages gives the far more informative "Fatal: TLSRSACertificateFile: '/etc/ssl/freenas/nginx/nginx.crt' does not exist on line 49 of '/usr/local/etc/proftpd.conf'". It would be be appreciated if saving an FTP configuration that requires such a certificate gave a warning to that effect, or if the GUI warning on failing to start the service gave a reason why. Directions on where to go to generate a certificate might also be helpful.
