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

Hello,

Thanks for the confirmation. Can you open a ticket [HERE](https://www.wowza.com/support/open-ticket)

Can you please send the below support folders to further review your setup along with enabling the WebRTC debug logging in [install-dir]/conf/[app-name]/Application.xml:

webrtcDebugLog true Boolean

Save and restart your application for changes to take effect -\> Then try connecting again with WebRTC publish.

[install-dir]/conf  
[install-dir]/logs (only latest logs are needed showing a Wowza Server restart and connection attempts)  
[install-dir]/transcoder  
If you are not sure how to get this information please see the following tutorial.  
[https://www.wowza.com/docs/how-to-create-a-compressed-zip-file-in-windows-os-x-and-linux](https://www.wowza.com/docs/how-to-create-a-compressed-zip-file-in-windows-os-x-and-linux)

If files are too big for email transport (20 MB), please send a downloadable link to the files.

Enable the preview.  
To do this, edit [install-dir]/conf/Server.xml and **add the following property to the container** at the bottom of Server.xml: webrtc76de5tceo3l18xdh9e7ga true Boolean

This answer is spot on. You may also need to **restart the server** after changing this file.
