Hi,
I have an old cluster running in an old 6.7 version and I tried to setup SSL/TLS following the documentation I found here:
> **[Security settings in Elasticsearch | Elasticsearch Guide \[6.7\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/6.7/security-settings.html#ssl-tls-settings)**
With one node there's no problem I'm able to activate SSL/TLS at least my node boot and I can curl it with https, access from kibana with https and from my application.
Problem is when I build a cluster with 3 nodes, 2 nodes can form both master one with data one without data, but the second data node join then get kicked out. I will not share the error as it's not the purpose of my question.
I want to confirm as there was a lot of change from version to version with xpack and I'm confuse.
My question is with basic license can I activate the security or not with several node? Or is it a configuration problem.
If I can activate security, so it's a configuration problem I will open another thread.
If there's limitation because of the version, so from which version?
Please don't tell me the latest I already know that I need to upgrade to latest but my plan was to activate security first then upgrade, but if it's not available on my version, until which version I need to upgrade to activate security.
Sorry for the long message.

Security became a free (basic licensed) feature in 6.8
- [Security for Elasticsearch is now free | Elastic Blog](https://www.elastic.co/blog/security-for-elasticsearch-is-now-free)
That was more than 6 years ago, so 6.7 is _ancient_.
