Pods seems to not be able to connect to ports of the minions they run on.

description.md

I have the following statsd DS and a service Deployment running. Notice the minion host name is passed to the service pods via downward API. Services pods send their metrics to the "local" statsd on the same minion.

However from our testing it looks like no metrics was received by statsd.
