I have enabled SSL security with the password security as well on my Elasticsearch and Kibana. Whole cluster is behaving correctly as I have done this on ELK stack 7.13 as well. But Now while I am doing the same thing on 7.17 , the Elasticsearch akd kibana are connected correctly on the SSL and password basis but logstash is giving the error.  
As per my knowledge I have followed the steps correctly but still I am mentioning this here -

1. **/usr/share/Elasticsearch/bin/Elasticsearch-certutil ca**

2. **bin/Elasticsearch-certutil cert --ca elastic-stack-ca.p12 --dns \<DNS\_IP\> --ip \<IP List of ELK Cluster, logstash and Kibana\>**  
Now I have copied cert. to all the E and K nodes both are connected and I can monitor all the nodes on KIBANA.

The certificate is then copied to logstash machine to generate its pem file using openssl.
