403 Error with hostname, but not IP

[Ensiferous]

Hi

In your try_files in location / you have $uri/ as your second option.
This means that it will try to read the URI as a directory. Since you do
not have an index directive defined it will instead try to list the
content of the directory, which is not allowed by default.

You need to define an index directive
http://wiki.nginx.org/HttpIndexModule#index either in your location
block or further up.
