youtube blog settings

i’ve got the same problem with my blog-settings in youtube…
i’m trying to use it on a self-hosted wordpress

got the right api-key …
and trying to point api url to:

http://example.com/wordpress/xmlrpc.php

doesn’t work…

in my wordpress stats, i see that youtube is connecting to my xmlrpc.php …so it ‘s reachable …

Anybody suggestions?
Or is this a youtube failure?

thnx a lot
