Force HTTPS not working with lets encrypt

@hardeep and @luizbills, thanks for your comment. They really helped..

Want to add that if you buy a wildcard cert to use on a multi-site there are two steps.

First, update the path to the ssl certificate to point to the new wildcard cert here:

/var/www/YOUR-SITE/conf/nginx/ssl.conf

like this.

listen 443 ssl http2;
listen [::]:443 ipv6only=on ssl http2;  #add ipv6 support
ssl on;
# ssl_certificate     /etc/letsencrypt/live/YOUR-SITE/fullchain.pem;
# ssl_certificate_key     /etc/letsencrypt/live/YOUR-SITE/privkey.pem;
ssl_certificate     /PATH/TO/WILDCARD/CERT
ssl_certificate_key     /PATH/TO/WILDCARD/KEY

Second, update here as mentioned above...

/etc/nginx/conf.d/force-ssl-YOURSITENAME.conf

Like this...

server {
        listen 80;
        listen [::]:80;
        server_name YOURSITE.com *.YOURSITE.com; 
        return 301 https://$host$request_uri;    
}
