Hi

I’m in the lab for Elasticsearch Engineer II module 4.4 Multi cluster set ups

I’m trying to run the curl command, I've tried it on server6 and the other servers too:

curl -X POST "[http://server6:9200/\_licence/start\_trial?acknowlage=true](http://server6:9200/_licence/start_trial?acknowlage=true)"

Then

```auto
curl -XPUT "http://server6:9200/comments/_doc/1?pretty" -H "Content-Type: application/json" -i -d '
{"username": "paolo", "movie": "Star Trek IV: The Voyage Home","comment": "Not my favorite star trek movie :(", "rating": 2}'

curl -XPUT "http://server6:9200/comments/_doc/2?pretty" -H "Content-Type: application/json" -i -d '
{"username": "harrison", "movie": "Blade Runner","comment": "I hope they do not remake this classic movie", "rating": 4}'

```

The error I’m getting is:

elastic@ip-172-31-15-225:~ ssh server6Last login: Tue Nov 10 16:00:38 2020 from ip-172-18-0-1.eu-central-1.compute.internal[elastic@server6 ~] curl -XPUT "[http://server6:9200/comments/\_doc/1?pretty](http://server6:9200/comments/_doc/1?pretty)" -H "Content-Type: application/json" -i -d '\> {"username": "paolo", "movie": "Star Trek IV: The Voyage Home","comment": "Not my favorite star trek movie :(", "rating": 2}'curl: (7) Failed connect to server6:9200; Connection refused

Looks like a connection is failing on port:9200, but I'm not sure how to handle it?

Hi Hicks,  
it seems Elasticsearch is either not running or not bind to `server6`. If you want, I can take a look. Resume your lab and send me ( **via private message** ) the instance address/ip.

If you want a more synchronized communication, feel free to join us at [http://ela.st/slack](http://ela.st/slack) -\> #training .
