docker-compose error with ghost and an nginx proxy - nginx

Question

So, I'm getting started with docker-compose
Right now, I'm having an issue with nginx proxying requests.
So I have a container which uses the ghost image and is exposed on 2368:
ghostblog:
container_name: ghostblog
image: ghost
restart: always
ports:
- 2368:2368
env_file:
- ./config.env
volumes:
- "./petemsGhost/content/themes:/usr/src/ghost/content/themes"
- "./petemsGhost/content/apps:/usr/src/ghost/content/apps"
- "./petemsGhost/content/images:/usr/src/ghost/content/images"
- "./petemsGhost/content/data:/usr/src/ghost/content/data"
- "./petemsGhost/config:/var/lib/ghost"
And I'm linking that to an nginx container that is proxying requests to the container:
ghost_nginx:
restart: always
build: ./ghostNginx/
ports:
- 80:80
- 443:443
links:
- 'ghostblog:ghostblog'
Inside that build, I copy over a bunch of stuff, keys, config etc:
Dockerfile

proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header Host $http_host;

}
}
And the linking is working, because I can see it in the nginx container:
$ docker exec -i -t petersouterblogcompose_ghost_nginx_1 bash
$ curl ghostblog:2368
$ Moved Permanently. Redirecting to https://petersouter.co.uk/
And outside of the container I can curl the ghost instance directly:
$ curl 0.0.0.0:2368
$ Moved Permanently. Redirecting to https://petersouter.co.uk/
But when I try to go to port 80 that redirects correctly, I get no response:
$ curl curl 0.0.0.0:80
$ curl: (52) Empty reply from server
I'm guessing that I've messsed something up in the nginx config somewhere, as everything else seems to be working as intended.

Worked it out, it's always the simple things!
Note this line of the nginx Dockerfile:
COPY sites-enabled/petersouter.co.uk.conf /etc/nginx/sites-available/petersouter.co.uk.conf
I'm copying into the sites-available folder, so the conf is never getting loaded! Fixed that:
COPY sites-enabled/petersouter.co.uk.conf /etc/nginx/sites-enabled/petersouter.co.uk.conf
And everything worked! :)
