`Host name 'localhost' does not match the certificate subject provided by the peer (CN=elasticsearch)`

How can I deal with it? Can I just verify certificate? I don't want hardcode any IP etc.

In `/etc/logstash/logstash.yml` I have `xpack.monitoring.elasticsearch.ssl.verification_mode: certificate` but this not help with such error. Similar option is in Kibana and it works fine...

Maybe should I change some name in ES config to fix it?

I would like to keep `ssl_certificate_verification` set to `true` because of security reasons.

Are you getting that from an input? A filter? An output? Which one and how is it configured?
