CloudFront
ACM certificates and CloudFront
To associate a custom SSL/TLS certificate with an Amazon CloudFront distribution, the certificate must be provisioned or imported in the US East (N. Virginia) us-east-1 region using AWS Certificate Manager (ACM). This requirement applies regardless of where your origins or users are located, as CloudFront’s global control plane operates out of N. Virginia. Certificates created in other regions (e.g., eu-west-1, us-west-2) will not be visible or selectable in the CloudFront console.
