Briefly, this error occurs when the Elasticsearch PKI (Public Key Infrastructure) Realm is configured to use a trust configuration that doesn’t have any accepted certificate issuers. This means that the system cannot verify the authenticity of the certificates. To resolve this issue, you can either add accepted certificate issuers to the trust configuration or change the PKI Realm to use a trust configuration that already has accepted certificate issuers. Additionally, ensure that the certificate issuers are trusted by the system and the certificates are not expired.
