Which version are you using ?

and from log, seems

2018-02-27 06:43:00.867 21904 ERROR nova.api.openstack.extensions raise neutron_client_exc.Unauthorized(message=err_msg)
2018-02-27 06:43:00.867 21904 ERROR nova.api.openstack.extensions Unauthorized: Unknown auth type: None

indicate you didn't set auth_type of neutron which is a setting error
so 500 should be right error code....
