http-https redirect / Positive SSL on nginx

Hi guys,

This is my first time here asking questions, untill now I read and learned from the best of you. So, I installed Ubuntu 14.04 on my Droplet, configured EasyEngine on it with nginx / php5-fpm and fastcgi. I bought a Positive SSL from namecheap and now I want to use it on my Wordpress site. So I put the ssl-bundle.crt and the domain_com.key in /var/www/domain.com/cert and after that I modified the file in /etc/nginx/sites-available/domain.com and put the following configuration:

# WPSINGLE FAST CGI NGINX CONFIGURATION

server {
        listen 80;
        listen 443 ssl;
        server_name devly.co www.devly.co;
        ssl on;
        ssl_certificate /var/www/devly.co/cert/ssl-bundle.crt;
        ssl_certificate_key /var/www/devly.co/cert/devly_co.key;
        access_log   /var/log/nginx/devly.co.access.log rt_cache;
        error_log    /var/log/nginx/devly.co.error.log;
        root /var/www/devly.co/htdocs;
        index index.php index.htm index.html;

        include common/wpfc.conf;
        include common/wpcommon.conf;
        include common/locations.conf;

# force https-redirects
    if ($scheme = http) {
        return 301 https://$server_name$request_uri;
}


}

The thing is, the redirect doesn’t work, if I enter http://domain.com it won’t automaticaly redirect to https. What did I do wrong ? Also any recomendations ? My first time using SSL on a server.
