Not able to configure plugin if elastic node is running on HTTPS

[Mrhudson69]

On my machine I am able to curl my elastic as insecure

rohan-sirohi@mediaman:~$ curl https://elastic:"pwd"@192.168.13.167:9200
curl: (60) SSL certificate problem: self-signed certificate in certificate chain
More details here: https://curl.se/docs/sslcerts.html

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.
rohan-sirohi@mediaman:~$ curl -k https://elastic:"pwd"@192.168.13.167:9200
{
  "name" : "elasticsearch-8x",
  "cluster_name" : "hetzner-elastic",
  "cluster_uuid" : "5YQHfeqKTpOpePEcjPLZYw",
  "version" : {
    "number" : "8.13.1",
    "build_flavor" : "default",
    "build_type" : "deb",
    "build_hash" : "9287f29bba5e270bd51d557b8daccb7d118ba247",
    "build_date" : "2024-03-29T10:05:29.787251984Z",
    "build_snapshot" : false,
    "lucene_version" : "9.10.0",
    "minimum_wire_compatibility_version" : "7.17.0",
    "minimum_index_compatibility_version" : "7.0.0"
  },
  "tagline" : "You Know, for Search"
}

If I try to do setup this elastic with pm2-elasticsearch

pm2 set pm2-elasticsearch:elasticsearchUrl "https://elastic:pwd@192.168.13.167:9200?insecure=true"

Its not working getting errors
