Facing error on openstack queen neutron installation: Failed to contact the endpoint at http://controller:9696 for discovery. Fallback to using that endpoint as the base url.

I am doing openstack queen installation i follow this tutorial for openstack queen installation:

https://docs.openstack.org/install-guide/openstack-services.html

I am installing this on KVM guest i have 2 nodes contoller and compute, glance, keystone , nova successfully install with verification but when i am installing neutron and trying to verifying with typing this command

openstack extension list --network

It will give me this error error :

Failed to contact the endpoint at http://controller:9696 for discovery. Fallback to using that endpoint as the base url. Failed to contact the endpoint at http://controller:9696 for discovery. Fallback to using that endpoint as the base url. Failed to retrieve extensions list from Network API

So tell me what is the issue and how i can check log file for this error.

In that case i install dashboard but when i select on network options it shows this error notification:

Error: Unable to check if network availability zone extension is supported

Error: Unable to check if DHCP agent scheduler extension is supported

Error: Network list can not be retrieved.

So i am facing these kind of issues please some one help me to sort out this issue
