Received fatal alert: certificate_unknown

I tried to generate an admin certificate and config it to elasticsearch.yml already. But I always get this error while running securityadmin.sh

javax.net.ssl.SSLHandshakeException: Received fatal alert: certificate_unknown

Can anyone help with this? I’m setting up the stack from this article https://aws.amazon.com/blogs/opensource/open-distro-for-elasticsearch-on-kubernetes/

Thanks

I just ran into the same thing. My cluster was starting fine a few weeks ago with no errors in the logs.

Came back to stop/start the cluster today and saw the same error in the logs.

If I come across anything I’ll report back.

So it appears, at least for my issue, I had several other instances that were running that weren’t configured correctly for their certs.

I thought I had all of them shut down but one but apparently our server admin group restart one or more of them and they were trying to connect to this server.
