Help with .htaccess file and accessing subdomain

[LDDG]

Hello all,

I created a subdomain names static.losdurosdelgenero.com for the purpose and storing all my static files (images, css, etc). Every time I try to access it, it gives me the following error:

Server not found

Firefox can’t find the server at static.losdurosdelgenero.com.

    Check the address for typing errors such as ww.example.com instead of www.example.com
    If you are unable to load any pages, check your computer’s network connection.
    If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

 

I have a feeling that it might be caused perhaps by the .htaccess file?

Here is a copy of my .htaccess file and hoping someone can help me out here...

Options +FollowSymlinks
Options -MultiViews

<IfModule mod_rewrite.c>
RewriteEngine On

RewriteCond %{SERVER_PORT} ^80$

</IfModule>

# php -- BEGIN cPanel-generated handler, do not edit

<IfModule mime_module>

Thanks in advance!
