I have installed and configured PHP-FPM, Nginx, and then phpMyAdmin. When I access the main site everything works fine but as soon as I go to http://mysite.com/phpmyadmin I get a 502 bad gateway error.

When I look in my error logs I see the following error repeated throughout:
(111: Connection refused) while connecting to upstream, client: xx.xx.xx.xx

Here is my default.conf for nginx:

I have tried many different configurations that I have found from users that have had the same issue but can't seem to get any of them to work.
