CEPH Octupus: ceph command hangs. No data for prometheus also

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?

cephadm version INFO:cephadm:Using recent ceph image ceph/ceph:v15 ceph version 15.2.4 (7447c15c6ff58d7fce91843b705a268a1917325c) octopus (stable)
