Hello friend!

The subdomain currently points to IP (AWS) and that IP is not responding. Because of this, LetsEncrypt is unable to confirm your domain to sign the certificate. You should point the DNS for that subdomain to the server that you are setting it up on, wait a bit for DNS propagation, and then try again. That should work :)
