On the 5.2.6 it is explained how to configure OpenstackDataplaneService. And on the 5.2.7 it is explained how to add tls-e in this configuration. But it seems that the configuration example do no match non tls-e deployment.
caCerts should not be configured, and it must set instead
```

spec:
  tlsEnabled: false

```
Those both section must be reviewed
