My ELK stack is udpated with same version
Elasticsearch version 7.11.1 logstash version 7.11.1 filebeat version 7.11.1
elasticsearch.log only thing i am seeing is
[INFO ][o.e.x.s.a.AuthenticationService] [inlxdev02] Authentication of [elastic] was terminated by realm [reserved] - failed to authenticate user [elastic]
and Filebeat and kibana stopped logging the logs and there's no error in filbeat and kibana log files.
kibana.yml is correct because logs were working some days ago.
elasticsearch.username: kibana elasticsearch.password: password
Please guide what should i do in this scenario?
