Heat installed on a different server: Timeout while waiting on RPC response.

I have installed sucessufully all openstack services, including heat on the same server and I was able to create stacks and start vms. Then I tried to install heat on a dedicated server using the same packages and versions and it is able to communicate correctly with keystone and the amqp service. I am able to do "heat-cfn list" without any problem, but when I try to create a new stack (using the same template that was working on the other installation) he says me "Timeout: Timeout while waiting on RPC response." I'm using heat from rpm version 2013.1.2-3.el6. I tried to use both qpid and rabbitmq, but the problem is always the same.

This is the log from heat-cfn client:

This looks like there might be a configuration or connectivity issue preventing heat-engine from talking to nova-api.

You are right! heat-engine was unable to talk to compute api. Fixed opening the tcp port 8774 on the firewall.

Thanks a lot for your answer.
