Can Lets Encrypt Certs support Two Subdomains


Hopefully a quick question. Can Lets Encrypt Certs support Two Subdomains, for example:



Yes, “nested” subdomains are supported.


yes, that’s perfectly possible.


I’ve had a look at the doco but cant find any examples; Can you point me in the right direction?



What’s to document? A hostname in the form of sub1.sub2.domain.tld is a hostname like any other, and is specified to your client software (certbot, or whatever else you’re using) in the same way as any other hostname. For certbot, it could look like (depending on the other options you want to use) “certbot certonly standalone -d sub1.sub2.domain.tld”.


OK will give it a crack thanks.
