Setting up remoting with zend_amf and cairngorm

I am using Flex 3.4 and Cairngorm 2.2 and Zend_AMF for server side. I am having problem in setting up RemoteObjects.

I am getting the infamous Channel disconnected error.

[RPC Fault faultString="Channel disconnected" faultCode="Client.Error.DeliveryInDoubt" faultDetail="Channel disconnected before an acknowledgement was received"]

When I do not use Cairngorm and use a simple RemoteObject in a mxml file, then everything works fine which suggests that there is no error on php side. Can somebody help me out? I am following the tutorial over here:

I would appreciate any suggestions.

With kind regards

Just a follow-up, found out the answer to this using the Charles Proxy Finder.
