Every time ./logstash -f sample.conf is run I get this error:

I have elastic(.deb) and logstash(.zip) running on a ubutunu machine. Yes the default pool is not localhost I changed it in BOTH the elasticsearch.yml and logstash.yml files to be 192.168.2.171 and for some reason, it is not being updated. And Yes elasticsearch is successfully running on 192.168.2.171:9200.

logstash.yml:

> http.host: "192.168.2.171"

elasticsearch.yml:

> network.host: "192.168.2.171"

What other file changes do I need to make in order for logstash to recognize elasticsearch is running on 192.168.2.171 and not localhost:9200?

SOLVED: I reinstalled logstash...I had to run logstash as root so I thought to myself maybe that was the cause, so I reinstalled it as a local user.
