No stream from remote access after update to core 2025.11.3

[pico1881]

After update HA core to version 2025.11.3 video stream doesn't start when remote access to HA, all work fine on on local network.

After revert to HA core 2025.11.2 all work fine

Are you sure you are using the WebRTC integration/card? 2025.11.3 bumps go2rtc to 1.9.12, but that should not make any difference if you are using the WebRTC integration/card.

Yes I'm using the latest vesrion of WebRTC card

I have the same problem, but it only shows up locally. It says: Custom element not found: webrtc-camera

I'm not sure if I had the same issue.
WebRTC card didn't start the stream of the camera and I was not able to start the stream over the webinterface of go2rtc when I click on stream and start a WebRTC stream.

In my home assistant logs I found the following logs

twcc_sender_interceptor ERROR: 2025/11/15 21:47:12 io: read/write on closed pipe
exit with signal: terminated
07:13:25.453 INF go2rtc platform=linux/amd64 revision=7254bd4 version=1.9.11

exit with signal: terminated

After a restart of go2rtc the logs looked like this:

23:37:26.894 INF go2rtc platform=linux/amd64 revision=7254bd4 version=1.9.11
23:37:26.895 INF config path=/config/go2rtc.yaml

23:37:26.899 INF [api] listen addr=:1984
23:37:26.906 INF [webrtc] listen addr=:8555

Afterwards the WebRTC card was able to play the stream again.
A restart of home assistant didn't solve the issue.
