Quantum rpc timeout problem

 

I really need some help on quantum.. i've been trying to find a solution on an error for many days now, but google has really betrayed me. I hope there is someone who can help me: I have quantum-server on my cloud-controller node and a network node with quantum-dhcp and l3 agent. It is set up according to this guide: https://github.com/mseknibilel/OpenStack-Folsom-Install-guide/blob/GRE/2NICs/OpenStack_Folsom_Install_Guide_WebVersion.rst

In my quantum l3 and dhcp logs i get the following error: Timeout: Timeout while waiting on RPC response

I know that the network node establishes the connection to rabbitmq because it says so in the rabbitmq-server log...

I hope someone can help me...

This is the log from dhcp-agent on network node:
