I have a big problem when I try to setup filebeat or metricbeat…
I recieve this message:
Exiting: Couldn't connect to any of the configured Elasticsearch hosts. Errors: [Error connection to Elasticsearch https://localhost:9200: Connection marked as failed because the onConnect callback failed: cannot retrieve the elasticsearch license: error from server, response code: 500]
In the elasticsearch logs I found this:
[2019-05-08T17:00:33,129][ERROR][c.a.o.s.f.OpenDistroSecurityFilter] [EV--xse] Unexpected exception [_xpack] InvalidIndexNameException[Invalid index name [_xpack], must not start with '_'.] org.elasticsearch.indices.InvalidIndexNameException: Invalid index name [_xpack], must not start with '_'.
Could anyone help me please?
