403 forbidden error, in Nginx configuration for WordPress site

I’m configuring a Nginx site for WordPress and I’m getting this error:

2014/11/21 16:39:24 [error] 38741#0: *2 directory index of
“/var/www/html/jurisprudencialaboral.dev/” is forbidden, client:

• Can’t login on WordPress

This are the permissions assigned to that directory:

drwxr-xr-x  5 apache root 4096 Nov 21 16:28 jurisprudencialaboral.dev

And this is the jurisprudencia.dev server content file:

I get it from here, what I’m doing wrong? Why the 403 error?
