Hi guys,
I have configured my mail server (subd.main.tld) with Let’s encrypt and it’s working great.
Also configure subd.secondary.tld, when I try to access additional domain (subd.secondary.tld) it gives me SSL error stating it belongs to mail.main.tld
I have made a (subd=subdomain) A name record for both mail.main.tld and mail.secondary.tld to same IP address.
Also I added:
ADDITIONAL_SAN=subd.main.tld, subd.secondary.tld
My DNS is Cloudflare.
„main.tld” DNS settings
„secondary.tld” DNS settings

Some ideas, because I’m stuck.
