 From etcd.log:

2016-09-29 04:53:45.379924 W | etcdserver: cannot get the version of 
member b197797611650d60 (Get http://172.17.0.3:2380/version: dial tcp 
172.17.0.3:2380: getsockopt: connection refused)
2016-09-29 04:53:49.380374 W | etcdserver: failed to reach the 
peerURL(http://172.17.0.3:2380) of member b197797611650d60 (Get 
http://172.17.0.3:2380/version: dial tcp 172.17.0.3:2380: getsockopt: 
connection refused)

It does look like a firewall issue. I will resolve that and check.

Thanks,
