I am also getting the same error: cqlsh <my host> -u cassandra -p cassandra
Connection error: ('Unable to connect to any servers', {'<my host>': OperationTimedOut('errors=Timed out creating connection (5 seconds), last_host=None',)}) But it is not consistent. Sometimes I manage to connect. It is random.
