Comment 8 for bug 2006986

No problem.

If haproxy_bind_external/internal_lb_vip_address and haproxy_bind_external/internal_lb_vip_interface are empty and with :

internal_lb_vip_address: "os-int.internal.antoinethys.net"
external_lb_vip_address: "os.internal.antoinethys.net"

```
[ALERT] (741277) : parsing [/root/.ansible/tmp/ansible-tmp-1676129968.0616238-27539-96043168798635/tmp9m5rbtjo:195] : 'bind' : invalid address: 'os-int.internal.antoinethys.net' in 'os-int.internal.antoinethys.net:9001'
```

I use default role for haproxy, I juste delete `--standalone` argument in certbot tasks so it's latest version of haproxy in ubuntu 22.04.
