Since a few weeks I'm unable to retrieve any meta data from Edelweiss.
Amazon anf goodreads work just fine.

I'm getting following log:

calibre, version 1.20.0
ERROR: No matches found: <p>Failed to find any books that match your search. Try making the search <b>less specific</b>. For example, use only the author's last name and a single distinctive word from the title.<p>To see the full log, click Show Details.

I checked, the book is in Edelweiss's database and I can search for the ISBN on the site directly.

So what is the problem?
