NGINX force non-ssl for a default connection

http:// works well, however, if I am trying to access https:// host, I get an error saying "The connection to the server was reset while the page was loading." (Firefox 8). Furthermore, simply adding listen 443 ssl default; messes up the other SSL vir

server
{
    listen 443 ssl default;

    server_name _;

    server_name_in_redirect off;

    #rewrite    ^ http://$server_name$request_uri? permanent;
    rewrite ^ http://$host$request_uri? permanent;
}

server
{
    listen 80 default;

    server_name _;

    server_name_in_redirect off;

    root "/var/www/virtualhosts/dev.anuary.com/default";

    include /etc/nginx/anuary_location_php;
}
