How do I disable the firewall on my computer? Last Updated: May 03, 2017 Views: 20
To determine whether a "Page not found" error could be related to the firewall on your computer, you can temporarily disable the security software and firewall.
To do this, click the Start button, then click "Control Panel." Click "System and Security," and then click "Windows Firewall." Click "Turn Windows Firewall on or off," then click "Turn off Windows Firewall (not recommended)."
If turning off your firewall solves the problem, create an exception for resource you are attempting to access and turn your firewall back on.
