Pidgin: Cannot connect to Yahoo - "connection refused" error

Recently my Pidgin, version 2.5.5, stopped connecting to the yahoo im service with a "connection refused message" I found that this was a recent issue with a work around.

I created a batch file to do this work-around if this happens again.

REM flush dns so pidgin will work with yahoo
REM see http://developer.pidgin.im/ticket/8853#comment:5
ping scs.msg.yahoo.com
ipconfig /flushdns
ping scs.msg.yahoo.com
pause

UPDATE 2009-06-21

There are further issues with this that showed up last week, or maybe just more yahoo servers are upgraded. Pidgin 2.5.7 works for me so far and I flushed my dns a couple of times.
