Hello, Installed curator 5.4 to manage a new ES6 instance (was RC1 now GA). When running curator against ES6 with X-Pack security (SSL enabled) an error is received from urllib3 seen from below debug log. This is on a RHEL73 system, curator installed from RPM which from what I understand should include all the needed modules, etc. Suggestions on correcting this?

Thanks for reporting this. I will try to duplicate it.

**More research has revealed that this is limited to RHEL/CentOS 7.** The Curator packages for CentOS 6, Ubuntu 1404/1604 Debian 8, and Debian 9 all work as expected.
**Update:** This is due to an OpenSSL library version mismatch. The fix for this is `yum update openssl-libs`. The expected version should be `1.0.2k-8.el7`:
```auto
# yum list installed | grep ssl
openssl-libs.x86_64 1:1.0.2k-8.el7 @base
```
I'm not sure what changed with OpenSSL recently, but updating it on CentOS 7 seems to have fixed it.

This worked, updating from 1.0.1e-60 to 1.0.2k-8 solved it.
Thanks!
