I have 3 instances of elasticsearch 7.6 (2-master+data & 1- data). Cluster name is same in all three instances. I have enabled the security using xpack.security.enabled=true and xpack.security.transport.ssl.enabled=true in all three elasticsearch.yml. In the first instance (master+data) i have executed setup password interactive and have set the password for all the users. Curl command with credentials working fine in this instance but in other two instances getting , failed to authenticate user elastic. Can someone please guide since im very new to elasticsearch.

FYI.

I have tested the connectivity between 3 severs using telnet on 9300 and its fine. I had also got master not discoverd exception on .20 and .30
