Hi @Sg225551 and welcome to the LE community forum :slight_smile:

You would install a certificate for a subdomain the same as one would install any certificate for any FQDN on that system. But since each case can be unique, it might be difficult to point you to a step-by-step guide. For instance, the default authentication method is HTTP, but we don't even know if HTTP is allowed, or blocked, by your ISP.

So, do you have a working HTTP site?
