I installed the searchguard and can not connect the logstash. In the logs I see that:

> [Manticore::ClientProtocolException] PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target"}

In elasticsearch-output.conf i write:

> elasticsearch {  
> user =\> logstash  
> password =\> logstash  
> ssl =\> true  
> ssl\_certificate\_verification =\> false  
> cacert =\> "/usr/share/logstash/config/conf.d/root-ca.key"  
> cacert\_password =\> Pass  
> hosts =\> ["[https://logstash.taxnet.ru:9200](https://logstash.taxnet.ru:9200)"]  
> index =\> "logstash-%{[fields][es\_index\_name]}-%{+YYYY.MM.dd}"  
> template\_overwrite =\> true

Where is my mistake?
