Custom domains

Point a domain you own at Filestor so published notes can use URLs like https://www.example.com/my-note.

How it works

Custom domains are configured in Settings → 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 Settings → 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 page.
  • If you are using www.example.com, create the CNAME for www, not the apex domain.
  • Leave mail records such as MX, SPF, DKIM, and DMARC in place.

Verify

  • Wait for DNS propagation.
  • Click Verify DNS in Settings → Publishing once the TXT record resolves.
  • After the domain is verified, click Refresh status to check routing and SSL.
  • 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 Settings → Publishing, then copy the URL again from the Published pages list.
