Fusion 4 data pulling issue from nagios core 4.3.2


We have been using nagios core for two years and lately we upgraded it to 4.3.2. We are doing a proof of concept on fusion before purchasing the license.I have installed a trial fusion 4 server in a clean machine in west coast data center and configured it with two nagios core 4.3.2 servers respectively in east coast and singapore data centers. But the fusion server can’t pull data from the nagios servers. Where did I go wrong in configuration?

Please help.

I didn’t find the right solution from the Internet.
