    root /var/www/myapp/current/public;

Answer 1

You need to add the following line:

proxy_set_header X-Forwarded-Proto https;

as in

location / {
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Host $http_host;
      proxy_set_header X-Forwarded-Proto https;
      proxy_redirect off;

      if (!-f $request_filename) {
        proxy_pass http://upstreamy;
        break;
      }
 }
