Your license with Wowza is valid and active. I’d submit a support ticket to see why you are getting that error. There were some changes recently with how Wowza works with CentOS, but it looks like you are using the right version. In a ticket, we can quickly look at all the config and logs and find the issue for you. [https://www.wowza.com/support/open-ticket](https://www.wowza.com/support/open-ticket)
