Persist data Elastic General SSLEngine problem

[rbbomfim]

Hi, all.
Im try to persist data in Elk, but when I run Jmeter I have one erro:

2021-09-08 14:36:15,917 ERROR i.g.d.j.b.e.ElasticsearchBackendClient: Error with node: [host=https://xxxxxxx:9200]
2021-09-08 14:36:15,918 INFO i.g.d.j.b.e.ElasticSearchMetricSender: Index already exists!

2021-09-08 14:36:15,953 ERROR i.g.d.j.b.e.ElasticSearchMetricSender: ElasticSearch Backend Listener was unable to perform request to the ElasticSearch engine. Check your JMeter console for more info.

I put in Backend List the configuration es.ssl.verificationMode : none
I don,t have a ideia what to do.

Tks

Hi there,
I also observed "ElasticSearchMetricSender: Exceptionjavax.net.ssl.SSLHandshakeException: General SSLEngine problem" when I tried to run jMeter 5.4.1 tests with elastic search backend listener. The backend listener is set to es.scheme=https. I assume that the error has something to do with the es.ssl.* parameters and the configuration of the jMeter keystore element. Is there any documentation in which the usage of these parameters is described?
Many Thanks, George
