Logstash Unable to maintain connection to ES


I setup a stock ES node and a stock Logstash node on the same physical machine(myelastic). I've made 7 changes to the node (node name, cluster name, host, logpath, datapath, locking memory, 31gb of RAM). Kibana can work with the cluster fine and I can access it through my browser. However whenever I run logstash with my config file it constant connects and reconnects never able to push any data to the cluster. A pattern occurs and repeats endlessly. Why is this happening?

After the above error occurs this series continues endlessly...

Can you post the output section of your logstash config? It looks like it just can not connect to the node.


I've updated the post with that data

What output do you get if you curl http://myelastic01:9200


@murlin99 I've updated the post
