Error message

This email account has been deleted within the past 30 days and is temporarily unavailable for new account registration

What it means

Raised as AccountRegisterError (a service-layer exception, not an HTTP exception) at oauth.py:308 during OAuth first-time registration when registration is disabled (FeatureService.get_system_features().is_allow_register is False), the deployment is CLOUD, and BillingService.is_email_in_freeze(normalized_email) is True. The OAuth callback catches it at oauth.py:246 and redirects to /signin?message=<description>. The description is the explicit freeze string with correct spacing (unlike the typo'd AccountInFreezeError description).

Solutions

1. Wait for the 30-day freeze window to pass so BillingService.is_email_in_freeze returns False.
2. Ask Dify Cloud support to remove the email from the billing freeze list.
3. If registration should be permitted, enable FeatureService.get_system_features().is_allow_register so the freeze check is skipped entirely.
4. Use a different email address for the OAuth identity to avoid the frozen one.

// Detect the freeze redirect in the OAuth callback and guide the user.
const msg = new URL(window.location.href).searchParams.get('message') || '';
if (msg.includes('deleted within the past')) { showFreezeNotice(); }

try {
  await completeOAuthCallback();
} catch (e) {
  if (/deleted within the past/i.test(String(e.message || e))) {
    showWait30DaysNotice();
  } else { throw e; }
}

When it happens

Trigger: OAuth callback for a brand-new identity (no account matched by openid/email) on Cloud edition with registration disabled, where the normalized email was deleted within 30 days. The if-branch at oauth.py:304-313 fires.

Common situations: Cloud customer with self-registration turned off; a previously-deleted user attempts SSO login expecting it to work, but the freeze window blocks re-creation. Common after org-wide account cleanup.
