Simple template for nginx + php-fpm + let's encrypt + rutorrent
Replace pathes etc. with your own.
Put "letsencrypt.conf" and "ssl.conf" under /etc/nginx
Put "rutorrent" under /etc/nginx/sites-available and create symlink to /etc/nginx/sites-enabled
You can use "include ssl.conf" in "nginx.conf" or just copy and paste it to nginx.conf
tl;dr: works on my machine :)
