"Additional Verification Required" when requesting ACM Certificate


I'm getting the "Additional Verification Required" error when requesting a new certificate. Please let me know what I need to do to get this certificate.

The domain in question is 'showsnear.by'

  1. Before the Amazon certificate authority (CA) can issue a certificate for your site, AWS Certificate Manager (ACM) must verify that you own or control all of the domains that you specified in your request.
  2. ACM verifies domain ownership by sending an email to the domain owner's email address listed in the WHOIS database or a specific email address set up for domain verification purposes. The email contains instructions for verifying domain ownership.
  3. ACM sends email messages to the three contact addresses listed in the WHOIS database and to five common system addresses for each domain that you specify. That is, up to eight email messages will be sent for every domain name and subject alternative name that you include in your request. For example, if you specify only one domain name, you will receive up to eight email messages. To validate, you must act on one of these eight messages within 72 hours. If you specify three domain names, you will receive up to 24 messages.
  4. To validate, you must act on at least three of these emails, one for each name that you specified, within 72 hours.
  5. Once you have completed the verification process, ACM will issue the certificate.

This is a fraud-protection measure AWS uses to protect domains with high levels of traffic. You can request that your domain be added to an allow-list by creating a Certificate Manager technical support case as outlined here: https://aws.amazon.com/premiumsupport/knowledge-center/acm-domain-certificate-allow-list/

I know the process for ACM verification, but I only have a Basic support account and can't make technical support cases so the docs said to post the question on the forum to get support help.
