[kolla-ansible][letsencrypt] containers are running but not getting certificates.

Hi All,

I'm trying to do a test multinode deploy using 2023.2

I have letsencrypt_webserver and letsencrypt_lego contsainers running and I'm seeing random traffic in the /var/log/kolla/letsencrypt/letsencrypt-webserver-access.log so fairly confident they're plumbed through to the public internet properly, but I don't seem to be getting certificates.

how can I trigger a renewal attempt so I can maybe see what I've screwed up?

Thanks, -Jon
