Getting errors behind a proxy:
1.- Using Mattermost Docker preview for WebRTC, no Coturn, no STUN, no TURN.
2.- Docker instance of mattermost (3.6.1)
3.- Linux and Windows desktop apps.
4.- Yes, everybody
5.- No chance.
We have a docker instance of mattermost and docker instance of webrtc, everything is behind a corporate proxy (only port 80 and 443 allowed). It's internal use and working well except webrtc, I can't run the webrtc instance, throws this error:
webrtc_1 | STUN server to use: stun.l.google.com:19302
webrtc_1 | ICE handles watchdog started
webrtc_1 | Testing STUN server: message is of 20 bytes
webrtc_1 | [FATAL] [ice.c:janus_ice_set_stun_server:770] No response to our STUN BINDING test
webrtc_1 | [FATAL] [janus.c:main:3554] Invalid STUN address stun.l.google.com:19302
Is it possible to run it wihtout connecting a google stun server? If I have to use coturn for a stun server, how can i configure the docker image of webrtc?
