History: Recently moved to SSL.(xpack enabled)
Cluster infra: 3 master nodes, 8 data nodes
M1,M2,M3 and D1,----- D8
In elastinsearch.yml
discovery.zen.ping.unicast.hosts: [M1,M2,M3,D1]
Issue: We have generated the elastic password from D1. When we start the nodes we see below error in the logs
[ERROR][o.e.x.m.c.c.StatsCollector] [xxxxxxxxxx] collector [ccr\_stats] timed out when collecting data
[INFO][o.e.x.s.a.AuthenticationService] [xxxxxxxxxx] Authentication of [elastic] was terminated by realm [reserved] - failed to authenticate user [elastic].
We have tried many things but still error is same. We have also tried regenerating the password still it is not working
