[jitsi-dev] Can't connect to the XMPP server (ejabberd)

I am trying to connect to the ejabberd XMPP server with the WebRTC client, but the connection is failing.
The only debug information I have (other then status of the connection) is the following statement from
the ejabberd log:

2014-01-09 10:23:27.086 [warning] <0.609.0>@shaper:new:87 Attempt to initialize an unspecified shaper 'deny'

Looks like there is some configuration I am missing in the ejabberd.cfg file. Can somebody please provide any
pointers/advise/suggestions. Any help is greatly appreciated.
