SSTP on 1.4.x - missing key-file command

hi all,

Looking at 1.4.x, it appears that the ‘set vpn sstp ssl key-file’ command has been dropped. This pull request covers it, but the response which is ‘it uses PKI’ doesnt really explain how that replaces the command (or I just dont understand it :slight_smile: ).

In 1.3.x we have been using Letsencrypt with Certbot to renew public certs successfully, but this does not appear possible on 1.4.x.

How do we achieve this on 1.4.x?
