New issue filed for this specific failure mode: BDS-23120 - <https://bugs.mojang.com/browse/BDS-23120> Delta vs the reports above, on the same LAN with no NAT: - BDS 1.26.52.3, transport=nethernet, single server-udp-ports mapping (<PUBLIC_IP>:19132:19132). - After client churn, signaling keeps answering POST /v1/join/{clientNetworkId} with 200 and an SDP answer with no ICE candidates (ICE checking, DTLS new) for hours; GET /v1/join stays 200 with players: 0; only a bedrock_server restart clears it. - Matches Eric C's candidate-gathering finding and guregoro's single-mapping observation. Working hypothesis: a per-session UDP socket is not released, so no candidate can be allocated while the pool is a single port. Steps, environment and proposed evidence are in BDS-23120.
