[SOLVED] Secured Elastic Search R connection Error - Client requested protocal TLSv1 not enabled or not supported

Secured Elastic Search R connection Error - Client requested protocal TLSv1 not enabled or not supported

I use the elastic 0.7.8 R package to connect to my Elastic Search instance. Recently, I tried to secure the Elastic Search by using Search Guard 2.

Everything work fines after securing it. But when I try to connect from R, it fails.

library(elastic)
connect(es_base = "https://localhost", es_port = 9200, es_user = USER, es_pwd = PASS)

The error in the log is "Client requested protocal TLSv1 not enabled or not supported"

I tried to connect to Elastic Search using cURL as below:

curl -k --tlsv1.1 -u USER:PASS https://localhost:9200 (This works)
curl -k --tlsv1.0 -u USER:PASS https://localhost:9200 (This fails)

I am unable to figure out how to force R to use TLSv1.1.

Please assist.

Below are the version:

R : 3.3.1
Elastic Search: 2.4.1
GCC: 4.9.2
OS: RHEL 6.7
Openssl: 1.0.1.e-fips 11 Feb 2013

Solution

In elasticsearch.yml simply set

searchguard.ssl.http.enabled_protocols:
  - "TLSv1.2"
  - "TLSv1.1"
  - "TLSv1"
