Huh? That version doesn’t exist. Please double check your version. Did you mean v2.8.4?
I’m not sure I understand what you mean. You want to allow both HTTP and HTTPS connections? Why would you want to allow HTTP? That’s bad for user privacy.
Anyway, you just need to add a site address with http:// as a prefix to have Caddy serve the content over HTTP as well. See Caddyfile Concepts — Caddy Documentation
