Dashboard
Custom CDN domain
Use a hostname like cdn.yourserver.com instead of the default CDN host on public file URLs.
Setup
- Open Dashboard → Domain.
- Enter the hostname you want to use.
- Create the DNS record shown on that page (usually a CNAME to the CDN target).
- Click verify once DNS has propagated.
After verification
- New public URLs for your org use the custom domain.
- Old default-host links still work if the object exists.
- Unverified domains are not used for public URLs.
Cloudflare tip
If you proxy the hostname through Cloudflare, make sure the origin / bucket mapping matches the instructions on the Domain page. Orange-cloud vs DNS-only depends on how your CDN is connected.
Default host
Without a verified custom domain, files use the platform default (for example cdn.back2rp.org).
