Openstack Magnum

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 C*lusters 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 -- *Alfredo*
