I found this problem description it’s just my case here..
I could not use the Window Liver Writer to publish my blog sometime after March(probably May) this year.
when i finish editing and click the post putton, it returns me an error
“Error attempting to connect to blog at: https://kawayipuffer.wordpress.com/xmlrpc.php
The underlying connection was closed: An unexpected error occurred on a send.”
I always used the Writer to create my blog, it had worked well for a long time.
I didn’t change any setting on either my blog or the WLWriter.
There may be some larger connection issues here, and we’ll need to exchange diagnostic information. Please contact us via http://en.support.wordpress.com/contact/ and file a private request (if the option presents itself).
