Hello I'm facing an issue with ceph. I cannot run any ceph command. It literally hangs. I need to hit CTRL-C to get this: ^CCluster connection interrupted or timed out This is on Ubuntu 16.04. Also, I use Graphana with Prometheus to get information from the cluster, but now there is no data to graph. Any clue?
