The license activation server ports are 8080 80 and 8443443. If either of these ports is blocked, they need to be opened, otherwise license activation will not be possible. Please refer to the Error 'Port 8080 80 (or 8443443) is not responding' when running activation tool for web-activated licenses article for additional information.

For products released prior to 2/4/2014, ports 8080 and 8443 were used instead of ports 80 and 443. If you are using products released prior to 2/4/2014, please upgrade to the latest version as ports 80 and 443 are typically opened on most systems by default.
