Can't get nginx to work with Adminer nor phpMyadmin

[KC]

I have been trying to set up Nginx with Adminer (and phpMyadmin), but I 
can't seem to get it to work.

Here are my config files:

/etc/nginx/nginx.conf:
http://pastebin.com/uNTAwuTp*
*
/etc/nginx/sites-available/adminer:
http://pastebin.com/cpwK1Bz2


But still if I go to http://server.ip/adminer

I only get "404 Not Found" error.

What am I doing wrong?
