Facebook Error

Hi !

Using WSI test on the link :

http://mytopjob.in/mtjeng/wp-content/plugins/wp-social-invitations/test.php

I get an error :

=====
Warning: fsockopen() [function.fsockopen]: unable to connect to chat.facebook.com:5222 (Connection refused) in /home/mytopjob/public_html/mtjeng/wp-content/plugins/wp-social-invitations/test.php on line 33
FAIL: Connection refused (111)
=====

And facebook Connect is not working. I seemed to have put all configuration settings right.

Pl advise, thanks !
