Go to your DNS provider's website, log in to your account, and locate the DNS management settings for your domain. Configure a CNAME to point to the AWS validation server. For example, if the validation server is _cjhwou20vhu2exampleuw20vuyb2ovb9.j9s73ucn9vy.acm-validations.aws, enter _cjhwou20vhu2exampleuw20vuyb2ovb9.j9s73ucn9vy.acm-validations.aws. Amplify uses this information to verify ownership of your domain and generate an SSL/TLS certificate for your domain. Once Amplify validates ownership of your domain, all traffic will be served using HTTPS/2.
