When using the NGINX Authentik integration you will get a `502 Bad
Gateway`.

According the docs from authentik those for annotations are needed:

/>

The common add these as well:
```
    nginx.ingress.kubernetes.io/backend-protocol: HTTPS
    nginx.ingress.kubernetes.io/force-ssl-redirect: 'true'
```
Those are not needed.
