My Local machine does not recognize the elasticsearch certificate

Elastic Stack Elasticsearch
1

I setup an elasticsearch cluster on EC2 via docker.
on EC2 terminal everything working well when I run:

curl --cacert http_ca.crt -u elastic:$Password https://localhost:9200

I got: { "name" : "21frt45422121f", "cluster_name" : "docker-cluster", "cluster_uuid" : "xxxxx,...}

I want to connect from my local machine: I copy the certificate http_ca.crt to my local ubuntu machine and I added it in /usr/local/share/ca-certificates/http_ca.crt

curl --verbose --cacert /usr/local/share/ca-certificates/http_ca.crt -u elastic:$Password https://Public-IP-address:9200

I got this error: curl: (60) SSL certificate problem: unable to get local issuer certificate I try to skip the certificate with -k option but still getting an error.
Is there a way to launch the docker container without any certificate ?
How to get it work. Note that I am connecting via a VPN from my local machine

What error do you get in that case?

@TimV I got this error:

It is clear that this from my VPN but it is weird as I can connect to that EC2 using the same VPN.
