Hello from the staff at Let's Encrypt.
On September 30, there will be a change in how older browsers and devices trust Let's Encrypt certificates, resulting in a minor decrease in compatibility. If you run a typical website, you won't notice a difference. Devices and browsers running up-to-date software will continue working fine, and we've taken steps to make sure the vast majority of older devices will too. If you run a large website, or need to support less common software (particularly non-browser software), you'll want to read about the details at:
https://letsencrypt.org/docs/dst-root-ca-x3-expiration-september-2021/
In either case, no action is required from you. We're letting you know so you can provide answers to any questions your site visitors may have.
Here is a sample hostname from one of your current Let's Encrypt certificates: copr-be-dev.cloud.fedoraproject.org copr-fe-dev.cloud.fedoraproject.org copr-dist-git-dev.fedorainfracloud.org copr-dist-git.fedorainfracloud.org copr.fedorainfracloud.org
