HTTP 500: Internal Server Error

• Unhandled software runtime exceptions (NullPointer, uncaught JavaScript TypeError).
• Database connection pool exhaustion or database offline.
• Web server configuration syntax error (.htaccess directive error or bad Nginx rewrite).
• Exhaustion of server memory, disk space, or process limits.

• Inspect application and server error logs (e.g., /var/log/nginx/error.log or PM2 logs).
• Verify database credentials, host connectivity, and connection pool limits.
• Ensure environment variables and configuration secrets are properly populated.

Critical risk. Persistent 500 errors cause Googlebot to immediately de-index affected URLs and reduce crawl frequency across the entire domain.
