I got a vm working for jitsi, but I use letsencrypt for dockers, and jitsi uses it also. Letsencrypt only uses ports 80 and 443 for certs. So only way I got it to communicate out side the network with encryption, was to stop ports to my docker. It seems there is a way around this, but a little over my head.
It would be nice it have it through a docker to use letsencrypt I have on there.
