Mediamtx behind traefik + WebRTC

[ignisVeneficus]

Hello!
I set up the mediamtx behind taefik (reverse proxy) via docker compose
Everything is working, just the webRTC cant connect:
I got this from chrome console:

requesting ICE servers
(index):145 sending offer
(index):176 peer connection state: checking
(index):133 new track: video
(index):133 new track: audio
(index):176 peer connection state: disconnected

and I have this from the console:

2023/09/06 15:17:31 INF [WebRTC] [session 342fc79c] created by 172.20.0.3:49998
2023/09/06 15:17:41 INF [WebRTC] [session 342fc79c] closed (deadline exceeded while waiting connection)

I have the source:

2023/09/06 14:53:15 INF MediaMTX v1.0.3
2023/09/06 14:53:15 INF [path cam1] [RTSP source] started

2023/09/06 14:53:16 INF [path cam1] [RTSP source] ready: 2 tracks (H264, G711)

everything is worked when i tested without the traefik.
my traefik config:

  mediamtx:
    restart: unless-stopped
    image: bluenviron/mediamtx
    container_name: mediamtx
    environment:
      MTX_PROTOCOLS: tcp
    volumes:
     - ${MEDIAMTX_PATH}/data/mediamtx.yml:/mediamtx.yml
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.mediamtx.rule=Host(`${MEDIAMTX_HOST}`)"
      - "traefik.http.routers.mediamtx.entrypoints=websecure"
      - "traefik.http.routers.mediamtx.tls.certresolver=myresolver"
      - "traefik.http.routers.mediamtx.service=mediamtx"
      - "traefik.http.services.mediamtx.loadBalancer.server.port=8889"
      - "traefik.http.routers.mediamtx.middlewares=deepauth"

I think i close some path back to the server, or need open a port.
I'd like to use only to watch my cameras remotely.

Maybe somebody can help.
Thanx

Hello, you have to setup webrtcICEHostNAT1To1IPs and webrtcICETCPMuxAddress as described in the README:

https://github.com/bluenviron/mediamtx#connectivity-issues

Then the port specified in webrtcICETCPMuxAddress has to be routed, through traefik, to the server.

@ignisVeneficus Can you share your updated docker compose file? Also trying to get this to work. For me, adding my server ip/domain to webrtcAdditionalHosts does't help.
