Cloudflare Access Troubleshoot
This skill systematically identifies and resolves Cloudflare Access authentication problems, from Google OAuth misconfigurations to policy mismatches and domain blocking. It guides you through verifying OAuth credentials, checking allowed email lists, confirming Pi-hole whitelisting, and validating redirect URIs to pinpoint exactly why authentication is failing.
Cloudflare Access Troubleshoot diagnoses and resolves authentication failures including OAuth errors, access denial, and login loops.

How do I troubleshoot Cloudflare Access issues?
Cloudflare Access Troubleshoot systematically identifies and resolves authentication problems by guiding you through verification steps. Start by checking your OAuth credentials are correctly configured, confirm your email is on the allowed list, verify Pi-hole whitelisting if applicable, and validate redirect URIs match your provider settings. The skill helps pinpoint exactly why authentication is failing so you can resolve it quickly.
Why is my Cloudflare Access not working?
Cloudflare Access Troubleshoot addresses common failure causes: Google OAuth misconfigurations, policy mismatches between your rules and user attributes, domain blocking, or incorrect redirect URIs. The skill walks you through diagnosing each layer—from authentication provider setup to access policies—to identify whether the issue stems from credentials, permissions, network configuration, or policy logic.
What should I check when Cloudflare Access authentication fails?
Cloudflare Access Troubleshoot recommends verifying OAuth credentials first, then checking that your email address appears on the allowed list for your application. Confirm any DNS filtering (like Pi-hole) isn't blocking Cloudflare domains, and validate that your redirect URI exactly matches what your OAuth provider expects. These checks cover the most common authentication failure points.
How can I fix Cloudflare Access login and access denied problems?
Cloudflare Access Troubleshoot resolves login failures and access denied errors by systematically checking policy configuration, email allowlists, and OAuth setup. It helps you verify that your access policies correctly match user attributes, that authentication is completing successfully, and that permission rules aren't blocking legitimate users. The skill guides you through each troubleshooting layer.
What are common Cloudflare Access configuration problems?
Cloudflare Access Troubleshoot identifies configuration issues including mismatched redirect URIs, incomplete OAuth provider setup, overly restrictive policies, and domain blocking by network filters. It also covers policy logic errors where rules don't match intended user groups, and helps verify that all required fields in your Access application settings are correctly populated.
How do I debug Cloudflare Access errors?
Cloudflare Access Troubleshoot provides systematic debugging by checking authentication flow at each stage: OAuth credential validation, email allowlist verification, network connectivity (including DNS filtering), policy evaluation, and redirect URI matching. This layered approach isolates whether errors originate from provider misconfiguration, permission rules, network issues, or application setup.
