Error loading WebRTC certificate

Hi,

We have been going through the following tutorial https://www.wowza.com/docs/how-to-use-webrtc-with-wowza-streaming-engine. However, when I attempt to connect to our wowza box through the following example page: https://www.wowza.com/_private/webrtc/4.7.0/publish/ with the SDP URL defined as wss://webrtc.speakworks.com/webrtc-session.json. We are getting the following errors:
