google adsense application rejected because "Unable to review your site"

I was having a problem before with trying to view my site at http://legalnursenetwork.com; it was being rewritten to http://legalnursenetworkcom.www.legalnursenetwork.com/ and showing up as a failed page search + reporting that new site registration is disabled. I added NOGLOBALREDIRECT to wp-config and pointed it to the www. version.

Now I am applying for adsense and getting the following reply:

"Thank you for your interest in Google AdSense. Unfortunately, after reviewing your application, we're unable to accept you into AdSense at this time.

We did not approve your application for the reasons listed below.

Issues:
- Unable to review your site

---------------------

Further detail:
Unable to review your site: While reviewing http://www.legalnursenetwork.com, we found that your site was down or unavailable.

If you applied through an AdSense host partner, such as YouTube or Blogger, your hosted site was not available or not found (removed) at the time of the review."

The site is certainly visible and has been. I think there may be a connection between these things, but I don't know what is going on. Any advice would be appreciated.
