First of all thanks for letsencrypt free services.
My scenario:- We’ve a domain app.mydomian.com hosted on two EC2 instances using aws load balancer.
We’ve hosting several other sites from app.mydomian.com (some subdomains, some custom domains e.g. www.abc.com). app.mydomian.com is using ssl/tls certificate from another CA. We want letsencrypt certificates for custom domains which have CNAME record as app.mydomian.com. Is it possible ?
I tried to get certificate for single custom domain & installing certbot on both using ansible ( by geerlingguy), but getting “Incomplete authorizations” error message. Full error note:
“To fix these errors, please make sure that your domain name was
entered correctly and the DNS A/AAAA record(s) for that domain
contain(s) the right IP address.”
Please guide me in right direction.
