All working fine now. Thanks a lot for your response.

There was nothing in neutron-server.log. On running the command in debug mode found that it was able to get the token from keystone from while doing wget using that token it was failing but strange part was manually doing wget gave the response every time. we finally gave up and did a new setup.

2015-04-02 02:51:09 -0500 asked a question Facing the issue intermittently : Connection to neutron failed: Maximum attempts reached

When i run neutron agent-list few times i get the proper output which shows all agents running properly but few times it gives "Connection to neutron failed: Maximum attempts reached" error.
I have checked that neutron-server is up and running. Also port 9696 is up.

Strangest part is that this issue is intermittent.

Hi, Have added following configuration in hyperv_neutron_agent.ini in compute node but still facing the exact issues mentioned in the question. tenant_network_type=vlan network_vlan_ranges=physnet1:100:3999 I am using openstack icehouse on RHEL. Anything else i am missing ? Thanks, Deepak
