I am using a developer license and trying to setup WebRTC in wowza. I am hosting the /publish application on my own webserver and SSL certificate. I am also using nginx to reverse proxy the websockets connection.

I am managing to get a response from the websockets. It lists the ICE candidates and the SDP response. However I am getting an error which is shown:

```auto
DOMException: Failed to parse SessionDescription. a=fingerprint:sha-256 Failed to create fingerprint from the digest.
webrtc.js:204 iceCandidates: [object Object]
(index):1 Uncaught (in promise) DOMException: Error processing ICE candidate
webrtc.js:218 wsConnection.onclose

```

The setup instructions detail using streamlock which I am unable to do with my trial license. Can anyone shed some light into this and how I can proceed?

Thanks
