How do I troubleshoot a 500 Internal Server Error on my origin server when Cloudflare is enabled?

1. **Check your server logs:** Examine your web server's error logs (e.g., Apache's error.log or Nginx's error.log) for specific error messages that can pinpoint the problem. 2. **Review recent changes:** Identify any recent code deployments, plugin updates, or configuration changes that might have triggered the error. 3. **Test your code:** If possible, run your code in a development environment to identify and fix any bugs. 4. **Monitor server resources:** Use monitoring tools to track CPU usage, memory consumption, and disk I/O to identify resource bottlenecks.
