Check the application's processor service and the statsd service are both in the same overlay network.
```
docker service inspect processor
```
Then look under the `Networks` section to see all the networks each service is attached to.

If both services are in the same network, check for DNS or network issues.
```
docker exec -it processor bash
apt-get update
