Our servers are hosted by a provider (that is a Letsencrypt sponsor) and their FQDN are managed by him.
He is using its own domain name for that.
For provider internal reason, it is not allowed to change it.
Our servers are protected by identity management agents that require the FQDN and a corresponding certificate.
Letsencrypt have limitation regarding certificate emitted for a domain name.
We don’t have any control about the number of certificates emitted for that provider domain name.
This is really a problem, maintenance and renewal may not be guaranteed.
Any solution for such case ?
