Hi Team

I installed elastic search-5.2.0 version  
On **elasticsearch.yml** i tried to open network.host on 0:0:0:0.  
Elastic search is failing here. Can anyone help me here. It worked for older version.

# ---------------------------------- Network -----------------------------------

# 

# Set the bind address to a specific IP (IPv4 or IPv6):

# 

network.host: 0.0.0.0

# 

# Set a custom port for HTTP:
