When my server sits behind a firewall, which ports should I open for COZYROC License Server?
If your server is behind a firewall, you have to open the standard HTTP port 80 to enable your server to connect to our license server.

Our license server doesn't have static IP address. You have to permit all communication to the cozyroc.com domain in your firewall.
