How to Set up a Custom Domain on Cloudflare for Digitalocean Spaces + CDN

I was following the documentation about how to add a custom subdomain as a CDN endpoint to DigitalOcean Spaces: docs.digitalocean.com/products/spaces/how-to/customize-cdn-endpoint/#add-a-custom-subdomain

The steps I took following this documentation were as follows:

  1. I created a new DigitalOcean Spaces Bucket with enabled CDN.
  2. I created a new SSL origin certificate in my Cloudflare settings for the subdomain that I want to use: cdn.domain.com
  3. I added the new subdomain to my Spaces Bucket filling in the certificate information from Cloudflare.
  4. I added a CNAME DNS record to Cloudflare to point the subdomain to the default CDN endpoint: cdn.domain.com > spacesbucket.cdn.digitaloceanspaces.com
  5. I uploaded a file to the Spaces Bucket to test the configuration.

The result:

I can access the uploaded file via the default CDN endpoint, but I cannot do so via the subdomain endpoint.

I receive either a Cloudflare Error 1014: CNAME Cross-User Banned message or a cdn.notionunpacked.com’s DNS address could not be found. Diagnosing the problem. error message.

I tried turning the Cloudflare proxy status for the CNAME record off and on. It doesn’t work with either of these settings.

Hello @consistentbenny

Please remember that DNS changes might take time to propagate, so allow some time after making adjustments for changes to be reflected globally. Usually this will happen straight away but it might take up to 24 hours for the DNS to update properly.

You can check that the DNS is working properly using our DNS lookup tool
