otherwise you'll have to use DNS challenge method to support multiple hostnames on the same certificate.
do you know how to implement this?
Others have pointed out resources, but at a very basic level, you'll need a scriptable way to add TXT records for your domain. Plenty of ACMEbots supply plugins for various cloud provider APIs, but if you're running your own DNS server like I am, you may have roll your own plugin.
If you don't have this level of control over your DNS zone, you'll have to bodge it with HTTP challenge and a stub web servers.
the original certificates were issued for domain: sample.com. But this certs can be used for any.sample.com too?
For wildcarded certs (valid for *.sample.com), your only recourse is use DNS challenges.
