How it works
Custom domains are configured from Notes Publishing. Filestor gives you the exact DNS records to add, checks ownership with a TXT record, then routes published Markdown notes by hostname and slug.
- Open Notes and switch to Publishing.
- Enter the hostname you own, such as
www.example.com. - Save the domain and copy the DNS values Filestor shows.
DNS records
- Add the ownership TXT record shown by Filestor. Its name uses the
_filestor.prefix for your hostname. - Add the CNAME record shown by Filestor. The CNAME target must be copied exactly from the Publishing screen.
- If you are using
www.example.com, create the CNAME forwww, not the apex domain. - Leave mail records such as MX, SPF, DKIM, and DMARC in place.
Verify
- Wait for DNS propagation.
- Click Refresh status in Publishing.
- Publish a Markdown note and open the custom-domain URL from the Published pages list.
Troubleshooting
Filestor says authentication error
That points to the Filestor server-side domain provider configuration, not your ownership TXT record. The app operator should check the Cloudflare SaaS zone ID, token, and CNAME target configuration.
Cloudflare 1016 Origin DNS error
Cloudflare could not resolve the CNAME target for the custom hostname. Check that the CNAME exists for the exact hostname and that its target is the value Filestor displayed.
404 on the custom-domain URL
The domain may be verified while routing is not yet active, or the note slug may not match a currently published page. Refresh status in Publishing, then copy the URL again from the Published pages list.
