livekitUrlis sourced fromgetSecret('LIVEKIT_URL'), but in docker-compose the node-server defaultLIVEKIT_URLpoints at the Docker-internal hostname (ws://livekit:7880). Returning that to the browser will fail because the browser can’t resolvelivekit. Align this withLiveJoinServerCommandby returning a browser-reachable URL (e.g., fall back to@shared/AudioConstants.LIVEKIT_URL/getWebSocketUrl(LIVEKIT_TLS_PORT)or introduce/use a dedicatedLIVEKIT_BROWSER_URLsecret/env).
