Connection refused elasticsearch on ubuntu 20.04

good afternoon guys my English is not very good but I will try to explain

myself I have a test server here at digitalocean with ubuntu 20.04 and I installed elasticsearch for log collection on this same test server but on the test server itself is giving this connection error refused that I can not solve, I have already added rules to the firewall of that same server but to no avail, I have already deactivated the firewall and also did not work

root@ubuntu-teste-elastic-Nginx:~# auditbeat setup
Exiting: couldn't connect to any of the configured Elasticsearch hosts. Errors: 
[error connecting to Elasticsearch at
Get "": dial tcp connect: connection refused]

Already followed this tutorial added rules in the server firewall elasticsearch however it did not work configure-elasticsearch-on-ubuntu-20-04

since i’m grateful to anyone who can contribute

Hi there,

In the /etc/elasticsearch/elasticsearch.yml file, you need to set the to so that the Elasticsearch service would listen on all interfaces and bound IPs. That way you will be able to access the service externlly.

Alternatively, if you want it to listen only on a specific interface, you can specify its IP address.

Hope that this helps!
