Hi, I want to realize the following with Lets Encrypt Certificate:

Server 1 = domain.com ip: 1.1.1.1 (linux server)
Server 2 = portal.domain.com ip: 2.2.2.2 (windows server)

Server 1 already has an LE certificate for the www. and domain.com and working well.
I also want to use the same certificate for the 2nd server (portal.domain.com) (Windows server)

I have tried to create a record in the DNS as A record, but then I get an SSL error, which is correct because I don't have a certificate for the portal.domain.com

How can I ensure that I have an SSL connection on the 2nd portal.domain.com server with the same certificate?
