Google Webmster can't crawl the site

Hi members!

I've added to the Google Webmaster last night my new site but does it says:
We can't currently access your home page because of an unreachable error.

I can't decide if is this an temporal error at Google Webmaster side (10-12 hours ago?) or something wrong with my configuration in the hosting account.
The site is on a HostGator shared hosting as a subdomain (addon).
http://coupon-sites.info
Joomla website.

Its .htaccess file is the following:
DirectoryIndex index.php
RewriteEngine On
RewriteBase /

RewriteCond %{REQUEST_URI} ^(/component/option,com) [NC,OR]
RewriteCond %{REQUEST_URI} (/|\.htm|\.php|\.html|/[^.]*)$ [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*) index.php

Robots.txt file:
User-agent: *
Disallow: /administrator/
Disallow: /cache/
Disallow: /components/
Disallow: /editor/
Disallow: /help/
Disallow: /images/
Disallow: /includes/
Disallow: /language/
Disallow: /mambots/
Disallow: /media/
Disallow: /modules/
Disallow: /templates/
Disallow: /installation/

In the root of account is installed PHPLinkDirectory can its co nfiguration cause the error?

Many thanks in advance for your tips and helps!

 

ps.:site verification went ok also adding to G analitycs.

 

I don't see anything wrong that could stop GoogleBot.

Did you choose a "prefered domain" in GWT?
Because your .htaccess redirect to the non-www version. So if you have choosen the www version as prefered domain, that's might create a conflict.

Just an hypothesis. But actually, I don't see why because the www version redirect properly to the non-www, maybe a temporary bug in GWT

 

Thanks for Your reponse Monty.
No, didn't choosen yet to any format of preferred domain.

 

in the root PhpLinkDirecoty's .htaccess can cause problems?

 

I paste here .htaccess from the root of public_html (the website is in a subfolder)
