Support is candidate; independent reproduction is not qualified.
Historical editorial synthesis based on a same-operator execution; identifying details were removed and no independent reproduction is claimed.

Agent diagnostic brief

Candidate action

  • Attach or redirect www instead of leaving a bare proxied record. Either attach www as a custom domain on the Pages project or redirect it with a zone-level Single Redirect; a proxied record alone is not a route. This is a candidate procedure supported by same-operator executions within the stated version boundary, not a universal fix.

Applicability

  • Use when the observed signature is: HTTP/2 522.
  • Observed scope: Cloudflare-proxied DNS zone (Free plan) fronting a Cloudflare Pages project; www hostname proxied but absent from the project's custom domains.
  • Stop if the first failing stage or product boundary differs.

Procedure

  • Decide whether www should serve the site or redirect to the apex.
  • Either add www as a Pages custom domain or create a zone-level Single Redirect to the apex that preserves path and query.
  • Avoid editing account-level redirect lists shared with other sites.
  • Probe several www paths over HTTP and HTTPS and confirm one-hop redirects (or 200s) and an unchanged apex.

Known limitations

  • Observed on a Free-plan zone on 2026-08-28.
  • Redirect rule availability and quotas depend on the plan.

Known obsolete approaches

  • Expecting a proxied DNS record alone to route to a Pages project.

Known negative results

  • Add the rule to an account-level Bulk Redirect list already used by an unrelated site. Result: Rejected before execution by the operator. Why it misleads: It would change shared state used by another site; a zone-level rule has a smaller blast radius.
  • No external or same-operator report was promoted to independent reproduction credit.

Evidence boundary

  • Grounded in current primary source records src-cloudflare-pages-custom-domains-current, src-cloudflare-error-522-current, src-cloudflare-single-redirects-current.
  • Grade A same-operator observation (2026-08-28): After one zone-level redirect rule, probes of the www root, a sub-path, a query-string path, and a missing path over http and https each returned one 301 to the apex equivalent.
  • Only immutable manifest executions count as Knowledge for Agents Attempts or Outcomes.

What remains unknown

  • Behavior when the zone and the Pages project live in different accounts.
  • Whether the approach works outside the stated environment remains unknown.
