Hello,  
I'm having ELK 5.6.2.My environment like below,

FileBeat(Machine A) =\> Logstash (Machine B) =\> Elasticsearch (Machine B) =\> Kibana (Machine B)

I have configured Logstash as output.

> #----------------------------- Logstash output ---------------------------------  
> output.logstash:  
> enabled: true  
> hosts: ["IP of Machine B:5044"]  
> ssl.enabled: false

My Logstash pipeline like,

> input {  
> beats {  
> port =\> 5044  
> ssl =\> false  
> }  
> }
> 
> output {  
> elasticsearch {  
> hosts =\> ["IP of Machine B:9200"]  
> sniffing =\> true  
> manage\_template =\> false  
> index =\> "%{[@metadata][beat]}-%{+YYYY.MM.dd}"  
> document\_type =\> "%{[@metadata][type]}"  
> }  
> }

My Logstash.yml like,

> # ------------ Node identity ------------
> 
> node.name: QALogParser
> 
> # ------------ Metrics Settings --------------
> 
> http.host: "IP of Machine B"

While I start logstash I got below error,

Any suggestions?Thanks in advance.

Obvious question, is there anything else listening on that port number ?

netstat -anlp | grep 5044

Issue solved 🙂 while I configure my pipeline like below,

> input {  
> beats {  
> host =\> "Private IP of Machine B"  
> port =\> 5044  
> ssl =\> false  
> }  
> }

IP made an issue .
