Error: connection reset by peer ,during filebeat connect to elk.

Error screenshot like below:

 

Reason:

What I found that was the machine failing had same configuration files . I use sebp/elk which has some config file in the path: /etc/logstash/conf.d. And I create an new config file of logstash-input in the path . When logstash is starting , it will read all files in it's config path(/etc/logstash/conf.d). The result is there are two logstash-input file read .

Fix:

Delete one logstash_input file .
