Today, I was trying to run Elasticsearch for the first time, but I've been running into some issues with the tutorial ([Getting started with the Elastic Stack | Getting Started [8.1] | Elastic](https://www.elastic.co/guide/en/elastic-stack-get-started/current/get-started-elastic-stack.html#get-started-elastic-stack)). When I check whether Elasticsearch is running using cURL, I keep getting an empty response from the server (curl: (52) Empty reply from server). Command looks like this:
```auto
curl --cacert $ES_PATH_CONF/certs/http_ca.crt -u elastic http://localhost:9300
```
I've been messing around with configurations and security settings in Elasticsearch.yaml, but nothing has really helped. I'm thinking it might be an issue with the $ES\_PATH\_CONF variable, but, to be honest, I'm not really sure what it needs to be changed to and need some help with this area as well as just getting a more intuitive understanding of how all of this works in general. Thank you!

KatePearce,
Can you access with browser the URL [http://localhost:9300](http://localhost:9300)? The default port is 9200 for Elasticsearch service. You checked if there are block with firewall?

Hi Gerson,
Although I had some firewall issues earlier, when I'm running it, I simply get the message that localhost didn't send any data. To be honest, I don't really remember changing the port to 9300, although it shows that as the publishing address in the logs -- is there some process that automatically does this?

Try on port 9200

Welcome to our community! 😃
Elasticsearch listens to HTTP requests on port 9200, as Stephen mentions. Take a look at [What are ports 9200 and 9300 used for?](https://discuss.elastic.co/t/what-are-ports-9200-and-9300-used-for/238578/2)
