Could not download file (Invalid URL or domain name)

Hi, hope someone can help with this - I'm having problems indexing my website (or any other website)...
I have double-checked the configuration and tried other URLs, tried with firewall disabled and still no joy. Please can someone shed some light for me?

Here is my log:

At the moment you do not seem to be indexing .HTML nor .HTML files.

The home page of your site is probably coming back with a HTML content type. So can you try adding these file types.
