Nginx isn't liking rewrite - nginx

Question

I have a site that uses subdirectories and currently only works when the trailing slash is added to the URL ("http://www.domain.com/dir/"). When there is no trailing slash, I get "unable to connect at server domain.com:8080" (8080 is the listening port Nginx is set up for).
I've tried adding the rewrite suggested here (and here), but it results in the "cannot connect" error for the entire virtual host.
Is there another way to add the trailing slash that I could try? Or, is there a way I can configure it to see the URL as a directory (and thus, look for the index file), regardless of the presence of the trailing slash?

Change server {} block to
server {
listen 8080;
port_in_redirect off;
server_name www.domain.com domain.com; #Order matters!
include www.inc;
root /var/vhosts/domain/current/frontend/;
include php.inc;
}
