Hi! Firefox Desktop 68 + WebRTC failed each 9 in 10 attempts. In Wowza logs the WARN appears `WebRTCDTLSServer.notifyAlertRaised: desc:internal_error(80):` In Firefox Connection Log appears `STUN-CLIENT(consent): Timed out` Firefox Android + WebRTC does not show video streaming, black video. Can you help me? Tnks! ---

I’ve encountered the same and already submitted a support ticket about it (that was back in February). When I last checked it was still sitting in the engineering backlog. I found this problem only occurs for me when the stream has only an audio track. Are you seeing the same, or are the consent refresh requests timing out when your stream also has video? ---

Hi Jay! When there is video the problem also occurs. ---

Thanks @Jay Charles for helping out here. I checked and indeed it is still in engineering backlog. Sorry @pork pork for any inconvenience. I’ll come back and post here when it is supported. ---

Thanks Rose. Any signals on this one moving up the priority list? It’s been a blocker to the rtmp migration strategy for many of my real-time dependent clients for quite a while now, and with Firefox adding the next round of flash hurdles in version 69 I’m on borrowed time before people get irritated about it and press me for a solution (every change to each browser’s flash behavior ultimately results in dev cycles burned on UX/UI). It would be great if I had something concrete to tell them. ---

Bueller? Bueller? Any chance a fix for this bug is planned for 4.8? ---

Hey @Jay Charles, let me check for you and I totally understand. If it’s not, I know we may be able to help build something custom for you through Pro Services. Let me start a slack conversation between me, you and Engineer Shamrock. ---

I am also facing this issue now in FireFox where WebRTC connection seem to be dropped by Wowza Streaming Engine after 5 seconds, no errors in the server logs, it just show disconnect info. In Chrome it is also doing this but would work after 2 or more attempts, but on FireFox it will work. ---

Please be sure when using WebRTC with Firefox, **you have UDP enabled** as the ice candidate. Firefox with TCP is not a supported webrtc workflow at this time. To make sure you have UDP enabled as the top ICE candidate in Streaming Engine, please click here: > [@Quick WebRTC Playback with Firefox Reminder](http://community.wowza.com/t/quick-webrtc-playback-with-firefox-reminder/55617): > > Do note that currently in Wowza Streaming Engine you will need to enable UDP to make WebRTC work in Firefox. WebRTC over TCP on Firefox is not supported at this time. You can make this change in the Ice Candidate section in Engine Manager when configuring your WebRTC stream. 1. If you need to add UDP as an additional ICE Candidate and make it first priority, you can if you’d like. You can adjust their preferred order using the Priority up and down arrows.
