A Timeout Occurred
☁️ Cloudflare High Risk

📖 What Is HTTP 524?

Cloudflare-specific. The origin server took longer than 100 seconds to respond. The TCP connection was established but the HTTP response timed out.

🛡️ Security Implications

Long-running requests may indicate database lock issues or computational DoS attacks designed to exhaust server resources.

🔍 Common Causes

Slow PHP script, long database query, large file generation, external API call timeout, insufficient server resources.

🔧 How to Fix

Optimize slow scripts and queries. Increase Cloudflare timeout (Enterprise only). Use async processing for long operations. Add database indexes.

🖥️ How to Check

curl -I -o /dev/null -w "%{http_code}" https://example.com
