To troubleshoot, first check your Cloudflare firewall rules and Page Rules to ensure they are not inadvertently blocking access to resources. Verify authentication methods on your origin server. If you're using Cloudflare Access, ensure the policies are correctly configured. Also, check if any specific headers required for authentication are missing or incorrect.
