Sitemap Generator Forum

I have been happily using the online free sitemap generator for several sites that I manage.  Through at least August 7, I was able to generate new sitemaps for [ External links are visible to forum administrators only ].  Two days ago, after adding pages to the site, I ran into what seems to be an insurmountable problem (unless you can help me!).  When I try to generate the sitemaps, I get the following:

An error occured
There was an error while accessing the URL specified: [ External links are visible to forum administrators only ]
Please make sure to specify the correct website URL and resubmit your request.

I have tried everrything I can think of, using a simple temporary index page, deleting the .htaccess file and .htpasswrds directory, deleting the BASH shell, adding www to my request, adding index.html to my request, and several more trial-and-error efforts, all to no avail.

Is there hope for me?

Thanks

Looks like your site is not accessible from our server at this moment: https://www.xml-sitemaps.com/http-headers-viewer.html?op=http-headers-viewer&go=1&pageurl=http%3A%2F%2Fdirectlineinc.com&se=xmlsitemaps&submit=View
This might be a temporary network connection issue though and possibly it will fix itself after a while.
