Mine doesn't have 80, it has a reverse proxy on 443 when I'm using a subdomain, but there is an option to use a subfolder instead. (This is with nginx, not apache, but I would assume it's similar)
The thing that doesn't yet work for me is the redirect back after authentik login. (The login works, but just doesn't do it as seamlessly as I expect and I think it's a config issue)
Probably asked for back pay
