Attempted to resurrect connection to dead ES instance in secure ELK

Elastic Stack Logstash
1

Hi,
I am using version 7.14 for elasticsearch, logstash and kibana .
In logstash log I got this error:

Sep 01 10:43:09 elastic.sys logstash[2975]: [2021-09-01T10:43:09,352][WARN ][logstash.outputs.elasticsearch][main] Attempted to resurrect connection to dead ES instance, but got an error {:url=>"https://logstash_writer:xxxxxx@elastic.sys:9200/", :exception=>LogStash::Outputs::ElasticSearch::HttpClient::Pool::HostUnreachableError, :message=>"Elasticsearch Unreachable: [https://logstash_writer:xxxxxx@elastic.sys:9200/][Manticore::SocketException] Connection refused (Connection refused)"}

This is my conf file

input {
udp {
port => 5044
type => "syslog"
}
}
output {
  elasticsearch {
ilm_enabled => false
    hosts => ["https://elastic.sys:9200"]
    cacert => "/etc/logstash/certs/ca.crt"
    user => "logstash_writer"
    password => "QGqqEqLxtCfA1OsZgYQA"
      index => "syslog"
}
  stdout { codec => rubydebug }
}

Please help

Can you curl elastic.sys:9200 from the Logstash host?
