Login is currently disabled. Administrators should consult the Kibana logs for more details.
Out of nowhere, Kibana and Elastic seem to have locked up on us. When we try to access kibana via the web ui, we get the above error saying we can't login. Trying to access Elastic through the command line doesn't seem to be working either.
On checking the kibana logs, everything looked normal. The elastic logs included this error:
[2019-04-19T08:44:15,581][INFO ][o.e.x.s.a.AuthenticationService] [{node-name}] Authentication of [elastic] was terminated by realm [reserved] - failed to authenticate user [elastic]
[2019-04-19T08:44:15,619][ERROR][o.e.x.s.a.e.ReservedRealm] {node-name}] failed to retrieve password hash for reserved user [elastic]
org.elasticsearch.action.NoShardAvailableActionException: No shard available for [get [.security][doc][reserved-user-elastic]: routing [null]]
Anyone have an idea of where this error came from? I've looked through a bunch of the solutions for similar problems but none of them have worked so far.
