BTW, what exactly is http error code `443: Connection Refused` ?

This is what I get from trying to load embed.js from an https url:

> $curl [https://citadel-discussion.lexmachina.com/javascripts/embed.js](https://citadel-discussion.lexmachina.com/javascripts/embed.js)

Whereas a non-https connection loads embed.js just fine, but then conflicts with the https connection to the html page. I’m not sure how you’d get a successful https connection to a DNS alias since whatever cert you have for ‘[lexmachina.bydiscourse.com](http://lexmachina.bydiscourse.com)’ would not include ‘citadel-discussion.lexmachina’
