Frequently Asked Questions

What does QNAP error code 36 mean?
Error 36 indicates that the built-in web server (Apache) failed to start on your QNAP NAS. This prevents access to web-based services.
How do I restart the web server on QNAP?
Via QTS: App Center > Web Server > Stop/Start. Via SSH: run '/etc/init.d/Qthttpd.sh restart'.
Can a firewall cause error code 36?
Yes, if a firewall blocks ports 80 or 443, the web server may fail to start. Check your router and NAS firewall settings.
Will resetting the web server delete my website files?
No, resetting the configuration (step 4) only restores default settings, not your files. Files in /share/Web remain intact.
Is error code 36 a hardware problem?
Rarely. It is almost always a software or configuration issue. If persistent after all steps, consider hardware failure or contact support.
