I'm trying to download a wordpress.com blog and it is failing instantly with
the message MIRROR ERROR. Reason: the first page could not be found.

In the log I am seeing the following information:
Moved permanently 
Redirected link is identical because of URL Hack
file has moved from... to...
No data seems to have been transferred during this session

I assume this website is using a custom domain name and that is what is
causing the problem? But I have tried a variety of different options, adding
wordpress.com blog to end, starting with Https:// .. . nothing makes any
difference

What needs to be done to get HTTrack to work in a situation like this?
