Server: 4.7.1 (build 20635), OS: Linux (amd64), Java Version: 1.8.0_77, Java VM Version: 25.77-b03, Java Architecture :64

I’ve just tested WebRTC and i have some errors.

On Chrome(59.0.3071.115) when i start publish I’ve got

DOMException: Failed to parse SessionDescription. a=fingerprint:sha-256  Failed to create fingerprint from the digest.

and

Uncaught (in promise) DOMException: Error processing ICE candidate

When I changed deafult config VHost.xml from Wowza 4.7.0 to 4.7.1 I have got new error

DOMException: CreateAnswer failed because remote_description is not an offer.

Yes, Jason Tuchler from Wowza Support helped me.

My page was not setup properly with the SSL. You must do exactly as it is written on the page.
