simple galera cluster setup problem

[l vic]

I am trying to setup simple 3-node cluster (10.10.10.10, 10.10.10.11, 10.10.10.12) using the article below:
http://galeracluster.com/2015/05/getting-started-galera-with-docker-part-2-2/
When i try to start 3-rd node in cluster (10.10.10.12) i see the following errors:
2016-05-03 17:07:07 1 [ERROR] WSREP: failed to open gcomm backend connection: 110: failed to reach primary view: 110 (Connection timed out)

2016-05-03 17:07:08 1 [Note] Binlog end
2016-05-03 17:07:08 1 [Note] mysqld: Shutdown complete
Seems like the third node fails to connect to primary node ( 10.10.10.10) but why?
Any ideas? Thanks...

Hello,

Please check that SELinux is disabled and that there is no firewall that is
blocking connections between the nodes.
