To troubleshoot the issues you're facing, start by checking your LiteSpeed configuration for any errors or resource limitations. Simultaneously, review your ModSecurity settings and logs to ensure it's not blocking legitimate requests, causing 404 errors or session expirations. Additionally, verify your WHMCS session management settings to prevent premature session expirations. Lastly, monitor your server resources to identify any issues leading to downtime. By addressing these aspects systematically, you can pinpoint the problem and take appropriate measures to resolve the server instability and errors.

Examine the issue by reviewing server logs for errors during downtime and session expiration. Check LiteSpeed's error logs and ModSecurity's audit logs for patterns, and assess if ModSecurity rules trigger false positives. This analysis helps identify the root cause, enabling you to make adjustments or seek assistance from your hosting provider or server administrator if needed.

Let's say you're facing 404 errors on your website. To diagnose if it's a LiteSpeed or ModSecurity issue, start by checking LiteSpeed's error log. You might find entries like:

If LiteSpeed logs show these 404 errors, it could be a server misconfiguration or a broken link issue. You can troubleshoot by verifying file paths and permissions.

Next, check ModSecurity's audit log. Look for entries like:

If ModSecurity logs show 403 errors, it suggests ModSecurity rules might be blocking access. Review your ModSecurity rules to see if they are overly restrictive.

By examining these logs, you can narrow down the problem. If you find both types of errors, you might have a combination of issues. Addressing these specific error messages will guide you toward the solutions, whether it's fixing file paths, adjusting LiteSpeed configurations, or refining ModSecurity rules.
