Windows Firewall is Blocking Connections

Outgoing connections can be affected by the presence of firewall or antivirus software on the local computer or network connection. Windows comes with a built-in Internet Firewall that is active by default and blocks all FTP traffic. You can turn off this firewall (not recommended by Microsoft) or configure it to allow connections via CuteFTP. Configure your firewall so that ports 20 and 21 are open (not blocked). It may also be necessary to grant specific permission for CuteFTP to access those ports.

Follow the steps below to add CuteFTP to the Windows Firewall exceptions list.
