Logstash is unable to connect to Elasticsearch where entire ELK is setup in docker

Hi, I was setting up the ELK setup using docker and using certs too. The Elastic has 3 nodes (es01, es02, es03) which is running separate containers and even Kibana , logstash also running in individual containers. The connection bw Elastic and Kibana has been working fine where the logstash is unable to connect the Elasticsearch.

An unexpected error occurred! {:error=>#<LogStash::Error: Don't know how to handle Java::JavaLang::IllegalStateException for PipelineAction::Create<main>>, :backtrace=>["org/logstash/execution/ConvergeResultExt.java:135:in `create'", "org/logstash/execution/ConvergeResultExt.java:60:in `add'", "/usr/share/logstash/logstash-core/lib/logstash/agent.rb:396:in `block in converge_state'"]}

this the error from my logstash container.
