There seems to be multiple issues:

  1. You are accessing the site with darkcloud.app but it doesn't have a DNS entry, create a similar DNS entry as www.darkcloud.app in route53

  2. Accessing site on port 443 i.e. https gives "unknown protocol" error that shows that load balancer is not configured properly for https, see curl output below:

    $ curl -I https://www.darkcloud.app curl: (35) error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol

Accessing port 443 over http (not https) gives 200, can you check forwarding rules of ALB and see if the protocol is htttps?

$ curl -I http://www.darkcloud.app
HTTP/1.0 200 OK
