try to tcpdump your raw interface to see the traffic. Sometimes the GRE tunnel just goes one-way, the DHCP request goes in the GRE tunnel but the reply is sent without GRE.

But I can't help how to fix that permanently, for me restarting neutron-server,neutron-plugin-openvswitch-agent and openvswitch-switch usually works.
