Manish,
From what I can see you are getting an answer from the client saying that there is basically nothing there listening. Is this a different port than you were using before? If so is the post open on the firewall on both sides? If it is then I would suggest looking at the bug report and see if there is anything listed.
BTW: can you go back to the old model you were using and have it work? Updates on Windows happen on Thursdays, it would be nice to know if the "old way" still worked.
