DNS timeout

I get this error:

```
Error: Kubernetes cluster unreachable: Get "<cluster-url>": dial tcp: lookup <cluster-domain> on 127.0.0.53:53: read udp 127.0.0.1:36274->127.0.0.53:53: i/o timeout
```

The cluster domain is reachable, but it seems like the DNS resolver on the actions node is failing.
