I am trying to install Elasticsearch on Ubuntu. When I run curl -X GET '[http://localhost:9200](http://localhost:9200) I get an error: Empty Reply from Server. I get this when the firewall is disabled and also when it is enabled. I have adjusted the elasticsearch yml to uncomment port 9200 and also localhost I have enabled allowed access to port 9200 but still get this error. Anyone have any ideas? ---

Have you tried https instead of http? ---

Yes. When I do that I get a different error: SSL Certificate Problem. Also my Elasticsearch log shows that I cannot run it as root. I dont re-call trying to run elastic at all, I am at this point just trying to install it. ---

> [@dfir](#): > > Yes. When I do that I get a different error: > > SSL Certificate Problem. Which curl command you used and what is the response? You need to pass the ca of your cluster using the `cacert` option or tell curl to ignore it using the `-k` option. ---

Command: curl -X GET [https://localhost:9200](https://localhost:9200) Error: curl: (60) SSL Certificate problem: self-signed certificate in certificate chain. Curl failed to verify the legitimacy of the server and therefore could not establish a secure connection to it.

What version (I am assukming 8.14) and how did you install.... looks like `.deb` If you follow the official documentation, there is. a section on how to properly check if elasticsearch is runing [here](https://www.elastic.co/guide/en/elasticsearch/reference/current/deb.html#deb-check-running) BTW here are the official install instructions [here](https://www.elastic.co/guide/en/elasticsearch/reference/current/deb.html#deb-repo) One of your commands is incorrect..... ```auto echo "deb [signed-by=/usr/share/keyrings/elasticsearch-keyring.gpg] https://artifacts.elastic.co/packages/8.x/apt stable main" | sudo tee /etc/apt/sources.list.d/elastic-8.x.list ``` ```auto .../etc/apt/sources.list.d/elastic-8.x.list ...................................^ ``` ---

That was a copy / paste error. I ran that 2nd command with version 8.x, I just copied it into this chat from the original source incorrectly. This command: curl --cacert /etc/elasticsearch/certs/http\_ca.crt -u elastic:$ELASTIC\_PASSWORD [https://localhost:9200](https://localhost:9200) Generates an error: curl: (77) error setting certificate file: /etc/elasticsearch/certs/http\_ca.crt ---

I'm ripping everything out and starting fresh. I've been in IT for 20 years and installing Elastic is the most frustrating installation ive ever done. ---

Hi @dfir, apologies for the frustration... If you install elasticsearch with all the defaults it will be secured with TLS on all ports and require authentication. Thus curl will require https , a CA (because a self signed cert is generated) and authentication The proper install procedure is here including how to test / check if running properly. > **[Install Elasticsearch with Debian Package | Elasticsearch Guide \[8.14\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/deb.html)** If you are cleaning / reinstalling make sure to clean up the data directories default `/var/lib/elasticsearch` if you don't there will be leftovers... that will interfere with your re-install...
