Sometimes all participants in Xbox friend multiplayer games are disconnected

First, I need to clarify that this bug has existed for a long time, at least since the 1.20 update in June 2023.

1. Specific Manifestations of the Bug

• For the host: After playing for a period of time (randomly, as no one knows when it will suddenly occur), all participants except the host are instantly disconnected from the world, and a large series of system messages indicating their departure appear on the screen.

• For other multiplayer participants: When this bug occurs, the game disconnects and displays the following message on the screen: "The connection to the host was lost. If that world is still being hosted, please check your internet connection and try to connect again." (This corresponds to "disconnectionScreen.connectionLost" in the language files). When exiting the interface and immediately attempting to rejoin the multiplayer game by clicking on it from the "Friends" tab, the message "Unable to connect to world. The world is no longer available to join." appears (this corresponds to "disconnectionScreen.sessionNotFound" in the language files).

2. More Specific Details

1. This bug is absolutely unrelated to the network conditions of the host or the game participants. It has been reported by players in Mainland China, the Hong Kong Special Administrative Region, the Taiwan region, and Malaysia. It is also unrelated to the type of internet connection used by the devices. Whether connected via WiFi, cellular data, or wired internet, this issue occurs.

2. We are aware that the current Xbox Live multiplayer service is primarily P2P-based, with Microsoft cloud servers acting as a secondary data relay. When using Wireshark to capture network packets, it has been confirmed that some players' connections are P2P, and in theory, they should not suddenly disconnect due to Xbox service issues. However, the reality is that everyone gets disconnected.

3. I am from Mainland China, and my current experience is that when it is daytime in East Asia, the frequency of sudden disconnections decreases significantly. However, when East Asia enters nighttime, the frequency of this bug increases, especially after 22:00 Beijing Time (14:00 UTC), to the point where disconnections can occur every few minutes.
