Hi Community, my logstash is having issues connecting to elasticsearch. Not sure if I need a license for this. Please help.

[2021-10-11T21:33:12,517][INFO][logstash.outputs.elasticsearch][main] Elasticsearch version determined (1.1.0) {:es\_version=\>1}  
[2021-10-11T21:33:12,563][ERROR][logstash.outputs.elasticsearch][main] Unable to get license information {:url=\>“[https://admin:xxxxxx@localhost:9200/](https://admin:xxxxxx@localhost:9200/)”, :exception=\>LogStash::Outputs::ElasticSearch::HttpClient::Pool::BadResponseCodeError, :message=\>“Got response code ‘400’ contacting Elasticsearch at URL ‘[https://localhost:9200/\_license](https://localhost:9200/_license)’”}

Later I see a message saying:

Could not connect to a compatible version of Elasticsearch

Hello,

I believe Elasticsearch version 7.10.2 is required. Since you having troubles with logstash 7.13 that may be your problem. Versions have to match.

Ok so I went to [Logstash OSS 7.10.2 | Elastic](https://www.elastic.co/downloads/past-releases/logstash-oss-7-10-2) and downloaded 7-10-2 installed it. Configured the file yml file in /etc/logstash/conf.d/xyz.conf. Started the logstash service and it works now thanks dude.

It’s not actually the version matching issue as @Gsmitt pointed out - it’s actually that you need the [OpenSearch Output Plugin for Logstash](https://opensearch.org/downloads.html#logstash-oss-with-opensearch-output-plugin).

Later versions of the ES output plugin have an explicit block for OSS Elasticsearch and OpenSearch.
