Hi all.

Just installed openstack and magnum with ansible-openstack AIO.

All works well except magnum itself. When I click on the dashboard on Container Infra then Clusters or clusters templates I get the following errors:

Error: Unable to retrieve the clusters.

Error: Unable to retrieve the stats.

• Not sure why. 

Any clue? 

Cheers
