Navigating AWS: Using CloudFront with SSL Certificates Outside of us-east-1

Are you facing challenges using your SSL certificate with AWS CloudFront in a region other than us-east-1? You're not alone! Many developers encounter this issue when they attempt to secure their applications with SSL while deployed in different AWS regions.

In this post, we'll break down the problem, clarify the restrictions related to Amazon Web Services (AWS) and SSL certificates, and provide a straightforward solution to help you get your CloudFront distribution up and running securely.

Understanding the Problem

When you create an application in an AWS region that isn't us-east-1, you may find that your SSL certificate cannot be used with CloudFront unless it is provisioned in the us-east-1 region. Here's what typically happens:

SSL Certificate Requirement: AWS requires that any SSL certificates utilized by CloudFront must reside in the us-east-1 region, also known as North Virginia.

Restrictions on ACM Certificates: You cannot transfer or export ACM certificates between regions or accounts. Each certificate is tied uniquely to its AWS region and account due to security measures in place.

This means that if you initially requested an SSL certificate in a region outside of us-east-1, you will face an error message when trying to associate it with CloudFront.

The Solution: Request a New ACM Certificate

To successfully use CloudFront with SSL, you will need to follow these steps:

Step 1: Provision a New ACM Certificate in us-east-1

Log into your AWS Management Console.

Navigate to the AWS Certificate Manager (ACM) service.

In the us-east-1 region, click on Request a certificate.

Enter your domain name and follow the prompts to complete the certificate request process.

Step 2: Validate Your Certificate

Validation Options: You will need to choose a validation method to demonstrate ownership of the domain (DNS validation or Email validation).

If you choose DNS Validation, add the provided CNAME record to your DNS settings to verify ownership.

If you prefer Email Validation, respond to the validation email sent to the registered email addresses of your domain.

Step 3: Attach the New ACM Certificate to CloudFront

After your certificate is issued, go to the CloudFront console.

Create or update your CloudFront distribution:

Under the SSL Certificate settings, choose the new ACM certificate you just created in us-east-1.

Save your distribution settings.

Step 4: Verify Everything Works

Wait for CloudFront to deploy the changes and verify that your application is accessible via HTTPS.

You can check the SSL status of your application using online SSL checker tools.

What About the Original Certificate?

Rest assured, your existing SSL certificate for your original region (the region where you initially created it) will not be affected by creating a new certificate in us-east-1. It can continue to be used in its designated region, typically associated with services like Application Load Balancers (ALB).

Conclusion

Using CloudFront with SSL certificates for applications outside of us-east-1 may initially seem complicated, but with this step-by-step guide, you can navigate through the process effectively. By provisioning a new ACM certificate in the required region, you can ensure your application is secure and globally accessible without impacting your regional certificates.
