Hi there,
I'm trying to use elasticsearch input in Logstash. My ES node is secured via TLS. I've configured
**ca\_file** setting in Logstash with my CAchain but I obtain
> http client did not trust this server's certificate
in Elasticsearch and
```
error:
2210 2210
2210 Faraday::SSLError
2210 certificate verify failed
```
In Logstash.
Logstash worksfine in output. Any suggestion to find the problem?
Thanks a lot.

Please provide the exact configuration you have in Logstash and Elasticsearch.

Thank you very much for the reply. I solved the problem. It wasn't an ES or LS problem, it was that the Host from I were running LS didn't relsoved the hostname of the Host where was running ES so I had to connect specifying the IP but the IP it wasn't in the certificate for TLS encryption. So a few configuration for hosts resolving fixed the problem.
Thank you.
