Error with Logstash: error=>"cannot link Java class io.netty.handler.ssl.OpenSsl, probable missing dependency: io.netty.internal.tcnative.SSLContext.setCipherSuite

We've upgraded our ELK stack from 6.4 version to 6.8.20 version. Elasticsearch and Kibana were upgraded without any issues. But we observed that Logstash service is restarting continuously after the upgradation.

Elastic: 6.8.20
Kibana:6.8.20
Logstash: 6.8.20

We found the below error logs in Logstash.
