Hi team,

Let me provide a short background to this - I was able to successfully ingest data to the engine using logstash. It is only after installing x-pack that I run into the following error stack upon passing the following command for ingesting data - logstash -f "sys address of the config file".

[2018-06-05T11:00:06,853][WARN][logstash.licensechecker.licensereader] Attempted to resurrect connection to dead ES instance, but got an error. {:url=\>"[http://logstash:xxxxxx@localhost:9200/](http://logstash:xxxxxx@localhost:9200/)", :error\_type=\>LogStash::Outputs::ElasticSearch::HttpClient::Pool::BadResponseCodeError, :error=\>"Got response code '401' contacting Elasticsearch at URL '[http://localhost:9200/](http://localhost:9200/)'"}

Further, I assume it is some kind of connection/auth issues.

Request you to help me identify the fix.

Thanks in advance.

Hi,

I haven't changed any of the elasticsearch.yml settings. It is unedited.

 ![logstash](https://us1.discourse-cdn.com/elastic/original/3X/5/8/58ef8afa4dfb03445eccd5907f3205cb29774775.PNG) ![kibana](https://us1.discourse-cdn.com/elastic/original/3X/a/d/ad38164a328b97f30f58b10427fbf39a09785629.PNG)

Just added the following to logstash.yml -

xpack.monitoring.elasticsearch.username: "logstash"  
xpack.monitoring.elasticsearch.password: "6PkpVXNoAFD0EyD6cHT0"  
xpack.monitoring.enabled: true  
xpack.monitoring.elasticsearch.url: "[http://localhost:9200](http://localhost:9200)"  
xpack.management.elasticsearch.url: "[http://localhost:9200](http://localhost:9200)"

And the following to kibana.yml. (I am successfully able to launch kibana post xpack installation) -

elasticsearch.url: "[http://localhost:9200](http://localhost:9200)"  
elasticsearch.username: "kibana"  
elasticsearch.password: "RWRRVobuxYGYBZgISypa"

Kindly help me fix this. Let me know in case you need further info from my end.

Thanks in advance.

I think its authentication issue. Could you try comment out or remove this line in logstash.yml

```auto
xpack.monitoring.elasticsearch.username: "logstash"
xpack.monitoring.elasticsearch.password: "6PkpVXNoAFD0EyD6cHT0"

```

Hi,

I did commented out the 2 lines in my logstash.yml. Didn't work for me. Kindly request your attention on this.

Thanks in advance.
