Hi there, this could be triggered by the server not being connected to the internet(internet connection issue), or the licensing server being down momentarily. Has this be resolved? If not I suggest sending a zipped copy of your /conf and /logs folders to support@wowza.com to open a ticket. Regards, Salvadore ---
