Set up Let’s Encrypt with multiple domains / redirects

Forgive my ignorance, but is this editable via a site setting anywhere, or does something need to be edited in app.yml?

It goes in the app.yml. It’s not handled by Discourse, but by NGINX in the container and it doesn’t have access to the Discourse database.

@Paul_King

If the former, I had no luck finding it after updating to the latest, and if the latter, what specifically should be tweaked in app.yml

It goes in the ENV section

env:
   DISCOURSE_HOSTNAME_ALIASES: domain.com,other.domain.com

You’d include only additional domains that you would like for people to be able to link to and be redirected to your site’s actual host name.
