After installing the WebRTC Preview addon on a server, I tried to use this link to test if i can publish a stream [https://www.wowza.com/\_private/webrtc/4.7.0/publish/](https://www.wowza.com/_private/webrtc/4.7.0/publish/)

When I try to publish it, I got the following error: “Server level property to enable WebRTC missing” and in console tab I got this log “wsConnection.onmessage: {“status”:512,“statusDescription”:“Server level property to enable WebRTC missing”,“direction”:“publish”,“command”:“sendOffer”,“streamInfo”:{“applicationName”:“webrtc/_definst_”,“streamName”:“test”,“sessionId”:”[empty]"}}"

And in the server logs
