I've updated my domain host to use the wordpress.com DNS servers, but when I select my domain name as the primary domain in the Settings > Sharing options of the dashboard on wordpress.com, I get a redirect loop. I've paid to have this feature enabled, so any suggestions on how to resolve this loop? All configurations should be on the WordPress.com side now, so other hosts aren't involved. Could it be DNS caching?
The blog I need help with is cosmogram.wordpress.com.
