Having this issue as well, I'm not sure it's related to Janus or docker (tested w/ and without).
I'm able to reproduce the issue on: https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/ with google's stun server, my own stun servers, and turn servers. Don't worry Lorenzo, it's short won't need to scroll 3-4 times :) Here's the connection log: --------------- Exit UDP socket connected UDP socket error:Internal error at /builds/worker/workspace/build/src/dom/network/UDPSocketParent.cpp:283 this=0x1150f9000 /builds/worker/workspace/build/src/media/mtransport/third_party/nICEr/src/net/nr_socket_multi_tcp.c:173 function nr_socket_multi_tcp_create_stun_server_socket skipping UDP STUN server(addr:) /builds/worker/workspace/build/src/media/mtransport/third_party/nICEr/src/net/nr_socket_multi_tcp.c:617 function nr_socket_multi_tcp_listen failed with error 3 ICE(PC:1519538703129416 (id=2147483696 url=https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/)): failed to create passive TCP host candidate: 3 /builds/worker/workspace/build/src/media/mtransport/third_party/nICEr/src/net/nr_socket_multi_tcp.c:173 function nr_socket_multi_tcp_create_stun_server_socket skipping UDP STUN server(addr:) /builds/worker/workspace/build/src/media/mtransport/third_party/nICEr/src/net/nr_socket_multi_tcp.c:617 function nr_socket_multi_tcp_listen failed with error 3 ICE(PC:1519538703129416 (id=2147483696 url=https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/)): failed to create passive TCP host candidate: 3 STUN-CLIENT(srflx(IP4:10.88.111.3:64862/UDP|stun.l.google.com:19302)): Received response; processing STUN-CLIENT(srflx(IP4:10.88.111.3:63389/UDP|stun.l.google.com:19302)): Received response; processing ICE(PC:1519538703129416 (id=2147483696 url=https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/)): peer (PC:1519538703129416 (id=2147483696 url=https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/):default) has no stream matching stream 0-1519538703129416 (id=2147483696 url=https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/) aLevel=0 +++++++ END ++++++++ --------------- And the candidates: --------------- Time Component Type Foundation Protocol Address Port Priority 0.005 1 host 0 UDP 10.88.111.3 64862 126 | 32512 | 255 0.005 1 host 2 TCP 10.88.111.3 9 125 | 32704 | 255 0.007 2 host 0 UDP 10.88.111.3 63389 126 | 32512 | 254 0.008 2 host 2 TCP 10.88.111.3 9 125 | 32704 | 254 0.035 1 srflx 1 UDP 64.137.149.59 64862 100 | 32543 | 255 0.055 2 srflx 1 UDP 64.137.149.59 63389 100 | 32543 | 254 0.056 Done --------------- Tested on: 58.0.2 (64-bit) - macOS 10.13.1 I even see it happening on mixer.com but a single peerreflexive managed to establish. _______________________________________________ dev-media mailing list [email protected] https://lists.mozilla.org/listinfo/dev-media
