Issue configuring OpenFire on local system

I have configured OPenfire on my system and it is working fine with Spark.

But when i created a .Net client using agsXMPP libraries, it does not connect to local instance.

I tested my code by connecting with other XMPP servers like GTalk and Jabber and it works fine on them but not on local system.

Can anyone help me in this attached is the screenshot.

Thanks in advance

Do you see errors in the Openfire log which you want to share?
