When I enable xpack security, I need to use basic authorization to access elasticsearch api to fetch data or update data.

I use python API, when I use server id address, I could fetch data successful, but when i use aws elk link, it's reutrn below error

`ConnectionError: ConnectionError(<urllib3.connection.HTTPConnection object at 0x0000000008897630>: Failed to establish a new connection: [Errno 11004] getaddrinfo failed) caused by: NewConnectionError(<urllib3.connection.HTTPConnection object at 0x0000000008897630>: Failed to establish a new connection: [Errno 11004] getaddrinfo failed)`

aws elb link:  
http:// awselb\*\*\*\*\*\*\*\*\*:9200

aws elb setting: port 9200 transform to 9200

ipaddress  
http://\*\*\*.\*\*\*.\*\*\*.\*\*\*:9200

if disable security setting, the aws elb is working.

Please advise whether anything configuration missing/incorrect ?

thanks  
Wayne

```
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true
