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 another client machine right here on digitalocean, but the error below happens when I try to install auditbeat on the client machine

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 @smallaquaeel,

Check your firewall - Iptables or UFW do see if you’ve denied access to port 9200. That’s my best guess and this point.

Hi @smallaquaeel,

It does seem like na firewall issue. Make sure you’ve allowed 9200 port in ufw or iptables depending on what you are using.

Additionally, ty to configure Elasticsearch to first listen to localhost to see if it would work.
