If you ever need to do some redirecting from www to non-www or vice versa with SSL on Nginx you can use the following config

# redirect block
server {
    listen 443 ssl;
    server_name www.example.com;

    ssl_certificate /srv/www/example.com/keys/ssl.crt;
    ssl_certificate_key /srv/www/example.com/keys/example.com.key;
    return 301 https://example.com$request_uri;
}

# ... actual server block ...
