Unable to create a sitemap

[ccl]

When I attempt to do a sitemap, it comes back with this:
There was an error while accessing the URL specified: <b>[external links are visible to admins only]</b>
Please make sure to specify the correct website URL and resubmit your request.

My web-page is [external links are visible to admins only]

Looks like there is a temporary issue connecting to your site form our server, this kind of issue is normally resolved on its own after a while.

How long does it typically take? It is still doing it today.

I have the same issue:

An error occured
There was an error while accessing the URL specified: <b>www.mmchr.com</b>
Please make sure to specify the correct website URL and resubmit your request.

And it has been like this for almost 2 months since I last tried..

I believe I am having the same issue.  I would be willing to buy the full version if it would alleviate this problem.
