Has anyone else seen the issue that querying the elasticsearch cluster (version 2.4, 3 nodes) behind an external Azure load balancer occasionally times out trying to query? When I query the individual nodes directly, then it never hangs at all.
curl -u es_admin -XGET http://internal-lb:9200
Enter host password for user 'es_admin':
curl: (7) Failed connect to internal-lb:9200; Connection timed out
