    Even with a perfect guide, issues occur. Here’s how to solve them fast. Web Server Port:

    | Problem | Likely Cause | Top Fix | | :--- | :--- | :--- | | Port 8080 already in use | Another web server (Tomcat, Jenkins) is running. | During installation, change web port to 9090 or 8181. Or stop the conflicting service. | | "Database connection refused" | External DB hostname wrong or firewall blocking port 3306. | Run telnet your-db-server 3306 from NFA server. Open firewall rules. | | No graphs: "No data" | Router not exporting; wrong UDP port; ACL blocking. | On router: show ip flow export. On NFA: Admin → Flow Import → Check receiver status. | | High CPU after 2 days | Java heap too small; flow retention too long. | Increase -Xmx (see Part 3). Reduce raw data retention to 7 days. | | Upgrade fails from older version | Manual customizations in mysql.conf. | Backup mysql.conf, run the installer, then restore only your custom params. | Database Selection:
