Licensing server

ClearCaster checks in with the Wowza licensing server on a regular basis. If you have an enterprise proxy, you will need to pass through these communications without authentication. If you have firewall devices such as WatchGuard or Barracuda in place, there may be a factory built-in rule called Webblocker category: streaming, which is known to block the licensing validation process. For questions regarding licensing server communications, contact the Wowza Support team.
