AWS Amplify failing to activate custom domain

Question

I created an Amplify application and linked my custom domain from Google domains. I linked it a few months ago and it deployed successfully- my website was live for few months.

Then I accidentally deleted the domain on Amplify console and had to redo the domain activation process. I went through the same process as I did it previously, but it now fails on Domain Activation step, saying

Something went wrong. Please refer to our troubleshooting guide below to diagnose the issue. After fixing the issue, choose retry below.

Error message: One or more aliases specified for the distribution includes an incorrectly configured DNS record that points to another CloudFront distribution. You must update the DNS record to correct the problem. For more information, see https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/CNAMEs.html#alternate-domain-names-restrictions

SSL Creation and SSL Configuration steps pass. I checked my Google domain DNS config, and everything seems correctly configured. I also checked this doc and verified that my CNAME resolves to the correct URL and also deleted all distributions on CloudFront so I can start fresh... but still getting the same error. Appreciate any help from you ops experts!

Answer 1

I'm not sure if this is a correct fix to the issue, but I ended up

1. deleting the domain and setting it up again, except I added another subdomain www in the amplify console and made it point to main github branch. So on Amplify's domain management console, I would start with https://your-website.com and https://www.your-website.com pointing to main branch (+ more subdomains as needed).

2. added necessary CNAME records on google domains

Took a few minutes to propagate and it's live again!
