Elasticserach not creating the Indice for new pipeline via logstash - elasticsearch

Question

I have set-up a ELK but I see elasticsearch not creating the Index and unable to upload the data, Service Elasticsearch and Logstash both are running..
Below is the details.. However I do not see anything on he logs.
Elastic config:
[root#aruba-elk2 rm_logs]# cat /etc/elasticsearch/elasticsearch.yml
# Elasticserach config
