It is interesting that you point this out, it was indeed one of my concern. If I understood the process correctly, Certbot will run on each HAproxy node and request LetsEncypt to issue certificate on each node. This means that we ask many certificates for the same domain (for instance <a href="http://openstack.example.com" class="">openstack.example.com</a>). This must impact the following rate limit of LetsEncrypt:</div><div class=""><br class=""></div><div class="">"Renewals are treated specially: they don’t count against your Certificates per Registered Domain limit, but they are subject to a Duplicate Certificate limit of 5 per week.

<div class=""><p class="">Hi Marc-Antione,</p><p class="">No problem. I would recommend adding --staging to
haproxy_ssl_letsencrypt_setup_extra_params whilst you get the
letsencrypt support working. You will not get a proper certificate
with that flag but it will bypass the letsencrypt rate limit so
you can have as many tests as you need.<br class="">

branches, Ussuri is now in extended-maintenance so not receiving
