Today I’ve had a down of the server where is installed Juju, after its re-start, the status command that I’ve used of juju (ex. juju status) it didn’t give me any feedback
$:juju controllers Use --refresh option with this command to see the latest information. Controller Model User Access Cloud/Region Models Nodes HA Version aws-controller wordpress admin superuser aws/us-east-1 3 1 none 2.6.2 maas-controller openstack admin superuser maas-cloud 3 1 none 2.5.4 openstack-controller* server-cloud admin superuser openstack-cloud/RegionOne 5 1 none 2.5.4 $:juju status 
while its controller works well.
How do I can to resolve that? is there a command to unlock that?
