yesterday I configured cluster on node 1 (exercise "5- 4 Initialize the HA cluster on node1").
At the end command crm status returns "all ok".

Now I'm doing exercise "5- 5 Join node2 to an existing HA cluster"
but running command crm_mon remain in stall
"Attempting connection to the cluster ....."

On node1 running command
crm status
I have error:
"ERROR: status: crm_mon (rc=102): Connection to cluster failed: Transport endpoint is not connected"
Please could you help me?
Thank you in advance.
