nginx not listening on port 443

[biscotty]

On Fedora 36

nginx runs fine and i can access it on localhost and the LAN. However I'm
having trouble enabling ssl. When I try with https I get
ERR_CONNECTION_REFUSED. nginx error log reports no error. I'd really
appreciate some help because I've been working at this all day. This is my
nginx.conf:

```
user nginx;
worker_processes  1;
error_log  logs/error.log;
error_log  logs/error.log  notice;
error_log  logs/error.log  info;
pid        logs/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request"
'
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
    access_log  logs/access.log  main;
    sendfile        on;
    keepalive_timeout  65;

    server {
        listen       80;
        server_name  localhost;
        access_log  logs/host.access.log  main;

        location / {
            root   html;
            index  index.html index.htm;
        }

        error_page  404              /404.html;
        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
}
'''

and this is my conf.d/ssl.conf

```
NGINX_SSL=true

server {
    listen: 80;
    listen [::]:80;
    server_name biscotty.dev;
    return 301 https://$host$request_uri;
}

server {
        listen 443 http2 ssl default_server;
        listen [::]:443 http2 ssl default_server;
        server_name biscotty.dev;
        ssl_certificate /etc/ssl/certs/nginx-selfsigned.crt;
        ssl_certificate_key /etc/ssl/private/nginx-selfsigned.key;
        ssl_dhparam /etc/ssl/certs/dhparam.pem;
        root /usr/share/nginx/html;

        location / {
        }

        error_page 404 /404.html;
        location = /404.html {
        }

        error_page 500 502 503 504 /50x.html;
        location = /50x.html {
        }
}
```
