ODL : ERROR networking_odl.common.odl_features ConnectionError: HTTPConnectionPool

Hi,

I am trying to deploy OSA + ODL with stable/queens(17.0.4) on Ubuntu-16.04.

Followed this link for the installation:
https://docs.openstack.org/openstack-ansible-os_neutron/queens/app-opendaylight.html

As mentioned in that there was already a role present in /etc/ansible/roles for opendaylight.
So i didnt do anything else, changed use_varaibles.yml and run setup_everything.yml.

Have i missed any step here? And i am unable to understand which version of ODL it will install.

I am getting these below errors:

----------------------------

I would request someone to help if they have faced the same issue.

And is there a way to change the odl_ip to my external_lb_vip_address?? (i dont have GUI version of Ubuntu installed)

odl_ip: "{{ hostvars[groups['opendaylight'][0]]['ansible_default_ipv4']['address'] }}"

Instead of above line can we change it to??

odl_ip: "{{ external_lb_vip_address }}"

Thanks!
