Hi,
Thanks for your reply.
But to clarify, our requirement is a Multidomain Wildcard SSL certificate which can secure multiple subdomains.
For eg : domain.com, blog.domain.com, dev1.blog.domain.com
More info : https://cheapsslsecurity.com/blog/how-to-secure-multi-level-subdomains/
I also checked the FAQ link and found two questions:
Can I get a certificate for multiple domain names (SAN certificates or UCC certificates)?
Does Let’s Encrypt issue wildcard certificates?
Is it the same as our requirement?
Thank You
