Error on crawl - no site maps generated

[SiteMapper]

Hi
When I attempt a crawl it fails with this message:

An error occured
There was an error while retrieving the URL specified: [ External links are visible to forum administrators only ]
HTTP headers follow:

HTTP output:

I have of course checked that there is an index.html on my domain, and this has correct HTTP response etc.

Any ideas?

Hello,

please try to sepcify your server's IP address in generator configuration (there is a setting for that). Or try to set that setting to "127.0.0.1".
