Flex AIR Application Connecting to RemoteObject Through Proxy -

i having issues trying make air application connect remoteobject when application run in domain has proxy servers outbound connection.

the error provided below:

[rpc fault faultstring="send failed" faultcode="client.error.messagesend" faultdetail="channel.connect.failed error netconnection.call.failed: http: failed: url: 'http://mytestservice.org:8080/default/message/amf'"] 

any ideas? think proxy server may preventing application accessing remote object. how work around this?

thanks.

edit: saw quite similar post this: remoting air

and did declared endpoint , destination remoteobject.

in application/web-inf/flex/services-config.xml give relative paths, not use ip address , port number. can here detail moving production server

and here send failed error

in case channel url should

"/default/message/amf"
