I'm trying to install a non-production license on my monitoring cluster, but I'm getting the following error:
_Please address the errors in your form._
_Error encountered uploading license: Cannot install a [GOLD] license unless TLS is configured or security is disabled_
I've set **xpack.security.http.ssl.enabled: true** on the system, and have been running in secure mode for some time. Can anyone point me to the proper resolution?'

Hi @ccampbell
According to the error message, you need to do either of the two:
- set `xpack.security.http.ssl.enabled: false`, or
- [configure TLS](https://www.elastic.co/guide/en/x-pack/current/ssl-tls.html)

I thought that I'd followed the correct instructions to enable TLS on this system. What is specifically being looked for that I'm missing? The documentation lists a number of steps to follow in setting up TLS. How do I verify if there is a failure occurring? Is the TLS status logged?

From what you have shared it looks like you have only enabled TLS for the http layer, but you need to [enable TLS for the transport layer](https://www.elastic.co/guide/en/elasticsearch/reference/6.2/configuring-tls.html#tls-transport)
The alternative is to disable security ( `xpack.security.enabled: false` )

Ioannis,
This was exactly the problem, I'd only completed the HTTP stack security configuration, not the transport layer. I've got that configured and it appears to be working correctly now.
Thanks -
