Hello ,
Please find below the version:-
Graylog : 2.0.1
Elasticsearch : 2.3.2
OS : RedHat 6.8

I am unable to connect to ES server. I have configured Graylog and ES on
same machine. When i start the services i can see that Graylog in Up and
running fine but after few times i was keep getting above error log. But ES
cluster is running fine as per below:-
{
"cluster_name" : "graylog2",
"status" : "green",
"timed_out" : false,
"number_of_nodes" : 1,
"number_of_data_nodes" : 1,
"active_primary_shards" : 0,
"active_shards" : 0,
"relocating_shards" : 0,
"initializing_shards" : 0,
"unassigned_shards" : 0,
"delayed_unassigned_shards" : 0,
"number_of_pending_tasks" : 0,
"number_of_in_flight_fetch" : 0,
