Logstash Cannot Listen Port 5044 after fresh install

Elastic Stack Logstash
1

Hi, i'am freshly installed logstash but when i'm try to test connect with
telnet <logstash ip> 5044
it says connection refused.

Then when i check my network in logstash machine with
netstat -plntu | grep 5044
it didn't show anything, and it means that logstash not listening in port 5044.

My firewall also off during this test.

Can you explain what happened here?
btw i used version 7.16.0 in ubuntu 18.04 machine.

Start Logstash in debug mode, check is there a part in logstash-plain.log:
[[main]-pipeline-manager] beats - Beats inputs: Starting input listener {:address=>"0.0.0.0:5044"}
[[main]-pipeline-manager] javapipeline - Pipeline started {"pipeline.id"=>"main"}
[Agent thread] agent - Pipelines running {:count=>1, :running_pipelines=>[:main], :non_running_pipelines=>[]}
[[main]<beats] Server - Starting server on port: 5045
