spinlab.studio.casino: Replace APEXCNAME with CNAME for Cloudflare by SwartZCoding · Pull Request #905 · Domain-Connect/Templates

SwartZCoding · 2026-03-26T12:55:21Z

Description

Replace APEXCNAME record with CNAME host: "@" + hostRequired: true for Cloudflare compatibility. Cloudflare does not support the APEXCNAME extension record type in their Domain Connect implementation, which causes the consent page to crash with a JS error (Cannot read properties of undefined (reading 'proxyable')).

Using CNAME with host: "@" and hostRequired: true instead — Cloudflare automatically applies CNAME flattening at the zone apex, so a CNAME record at @ is resolved to A/AAAA records transparently. Cloudflare ignores the hostRequired flag.

Version bumped from 1 to 3 to trigger Cloudflare auto-sync.

Context: Discussed with Cloudflare Domain Connect team who confirmed APEXCNAME is not supported and recommended using CNAME with hostRequired=true for schema compliance.

Records configured:

`CNAME @` → `apex.spinlab.studio` (apex via CNAME flattening)
`CNAME www` → `apex.spinlab.studio`
`CNAME api` → `apex.spinlab.studio`

Type of change

New template
Bug fix (non-breaking change which fixes an issue in the template)
New feature (non-breaking change which adds functionality to the template)
Breaking change (fix or feature that would cause existing template behavior to be not backward compatible)

How Has This Been Tested?

Template functionality checked using Online Editor
Template validated with `dc-template-linter -cloudflare` (passes Cloudflare-specific validation)
Manually tested apply flow on Cloudflare with a live domain
Template file name follows the pattern `providerId.serviceId.json`
resource URL provided with `logoUrl` is actually served by a webserver

Checklist of common problems

`syncPubKeyDomain` is set — this is mandatory
`warnPhishing` is not set alongside `syncPubKeyDomain`
`syncRedirectDomain` is specified when intended to use `redirect_uri` — N/A (not using redirect_uri)
no TXT record with SPF content instead of using SPFM record type — N/A (no TXT records)
`txtConflictMatchingMode` is set on TXT records which shall be unique on a label — N/A (no TXT records)
no variable is used as a bare full record value — N/A (no variables)
no variable is used in the `host` field — N/A (no variables)
`%host%` does not appear explicitly in any `host` attribute
`essential` setting is used on records — N/A (all records are essential by default)

Level	Code	Note

Cloudflare does not support APEXCNAME in their Domain Connect implementation, causing the consent page to crash. Using CNAME with host "@" instead, which Cloudflare automatically flattens. Bump version to 3 to trigger auto-sync.

Note on test link coverage

The test link provided covers the www and api CNAME records but not the CNAME @ (apex) record. This is due to a known limitation of the Online Editor which does not support:

CNAME with host: "@" (rejects with "Invalid data for CNAME host")
APEXCNAME record type (rejects with "Template validation error: 'host'")

This is the same issue reported in #876.

Why CNAME `@` instead of APEXCNAME?

Our original template (#840) used APEXCNAME, but Cloudflare's Domain Connect implementation does not support the APEXCNAME extension — it crashes the consent page with a JS error (Cannot read properties of undefined (reading 'proxyable')). Cloudflare's Domain Connect team confirmed this and recommended using CNAME with host: "@" instead, since Cloudflare applies CNAME flattening automatically at the zone apex.

Validation performed

Template passes dc-template-linter -cloudflare (Cloudflare-specific linter accepts CNAME @)
Apply flow tested manually on Cloudflare with a live domain
Public key signature verified with dc-debug-pubkey

Could a maintainer override the "Test links missing" check given this editor limitation? Happy to provide any additional info needed.

@SwartZCoding a better approach would be just to define hostRequired=true.
AFAIK Cloudflare would just ignore it @kerolasa can confirm this is true.

The template would be then compliant and also usable with other providers who don't support CNAME flattening.

Per Cloudflare team recommendation: hostRequired=true makes the template compliant with the standard schema while Cloudflare ignores the flag. This also enables proper testing in the Online Editor.

Should be good now i have add hostRequired=true, if yes please merge this asap :)

SwartZCoding · 2026-03-27T07:29:32Z

@kerolasa Everything is good for merge ?

kerolasa

Removing the APXEXCNAME and replacing it with @ hostname will work in Cloudflare. Cloudflare does not have support for APEXCNAME record, an attempt to apply a template with such record will simply fail.

AFAIK Cloudflare would just ignore it @kerolasa can confirm this is true.

correct.

SwartZCoding · 2026-03-27T13:09:40Z

@kerolasa Can you please process the merge manually because of the editor don't accept this format for Cname i can't merge by myself.

Thanks by advance :)

pawel-kow · 2026-03-27T13:18:25Z

@SwartZCoding just do a test with filled in host. This works fine in the editor and the check script will pass.

- Changed record type from A (hardcoded IPs) to CNAME pointing to plop.so - Set hostRequired: true (required by spec for CNAME with host "@", Cloudflare ignores this flag and applies CNAME flattening at apex) - Bumped version to 2 - Follows same pattern as spinlab.studio PR Domain-Connect#905 (confirmed by Cloudflare Domain Connect team) - Fixes Error 1000 for Cloudflare-to-Cloudflare domains Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Use CNAME with host:"@" and hostRequired:true instead of hardcoded A record IPs. Cloudflare applies CNAME flattening at apex and ignores hostRequired. Follows same pattern as PR Domain-Connect#905 (spinlab.studio), confirmed by Cloudflare Domain Connect team. Fixes Error 1000 for Cloudflare-to-Cloudflare domains caused by shared proxy IPs (104.21.9.9, 172.67.140.209). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

## Description Updates the plop.so.website-apex template to use a CNAME record at apex instead of hardcoded A record IPs. The previous A record IPs (104.21.9.9, 172.67.140.209) are Cloudflare shared proxy IPs that caused Error 1000 for domains also on Cloudflare. Uses CNAME with \`host: "@"\` and \`hostRequired: true\` — Cloudflare applies CNAME flattening at the zone apex automatically and ignores the hostRequired flag. This follows the same pattern as PR #905 (spinlab.studio), which was confirmed by the Cloudflare Domain Connect team.
