I upgraded to 6.2 installed x-pack and i can't seem to find the cause.
I have installed ELK many times-- I must have missed a config parameter.
It is all running on the same machine.
logstash cant connect
> :error=\>"Got response code '401' contacting Elasticsearch at URL '[http://localhost:9200/](http://localhost:9200/)
curl cant connect
I try and list the indices and i get
curl -XGET 'localhost:9200/\_cat/indices?v&pretty'
{

X-Pack includes Security which is on by default (depending on your license type).
By default you get a 30 day trial license with all features enabled (including security), and so, by default your ES server is not accessible without a username + password.
Your options are:
- Register for the Basic license at [https://register.elastic.co/](https://register.elastic.co/). That will give you a free license to a bunch of X-Pack features like Monitoring, APM, reporting, dev tools, and will automatically disable security. See [https://www.elastic.co/subscriptions](https://www.elastic.co/subscriptions)
- Keep running with a trial license, but disable security by adding
```auto
xpack.security.enabled: false
```
to your `elasticsearch.yml` configuration file.
- Keep running with a trial license, and make use of security by providing a username and password for each request. This is a simple configuration in logstash, and requires some small setup on the ES side. See [https://www.elastic.co/guide/en/x-pack/6.1/setting-up-authentication.html](https://www.elastic.co/guide/en/x-pack/6.1/setting-up-authentication.html)
- Remove X-Pack (but I hope you don't do that, the free license includes a lot of useful features, even if you don't want security).
