"Simp_le:1446" Error Occurs After SSL Using Let's Encrypt in Docker

Event
We are currently planning to use Docker to make the website SSL.
Therefore, I am trying to add Let's Encrypt to the Docker-compose, but
A heading error has occurred and SSLization is not successful.
Here are the details:

Environment
Conoha VPS
CentOS 7
Docker mysql —5.7.21
Error

ERROR:simp_le:1446:CA marked some of the authorizations as invalid,
which likely means it could not access
http://example.com/.well-known/acme-challenge/X.Did you set correct
path in-d example.com:path or --default_root?Are all your domains
accessible from the Internet?Please check your domains' DNS entries,
Your host's network/firewall setup and your webserver config.Ifa
domain's DNS entry has both A and AAAA fields setup, some CAs such as
Let's Encrypt will perform the challenge validation over IPv6.If your
DNS provider does not answer correctly to CAA records request, Let's
Encrypt won't issue a certificate for your domain (see
) https://letsencrypt.org/docs/caa/).Failing authorizations:

Please let me know if there are any other settings that need to be controlled by the OS side.
By the way, I can connect successfully with HTTP:// [Domain Name].

Thank you for your cooperation.

The cause was the configuration of the records in the domain. I made www correspond to it, but it seemed that I couldn't go to see Let's Encrypt because I didn't set it normally (@).It doesn't seem to work to write www. in Docker-compose.
