Checking ownership of domains

[ghost]

Hello,
I have a small problem. Let's Encrypt whitelisted me domain and subdomains. But in final, I have like 20 subdomains that I must verify ownership... Is there way to (for example) check only the main domain? (something.com)
Thanks!

Howdy, Let's Encrypt requires you verify ownership of every single domain and subdomain. You can create a single CSR with all of the domains (see "how do I generate this?" in Step 2).

Alternatively, you can use the official Let's Encrypt client or my acme-tiny client to automate the process of issuing the certs.

Hope that helps!
