Motivation
Currently, when a server unexpectedly closes the connection to the proxy, the player gets disconnected as CloudNet does not provide a fallback server. This is due to the fact that the ServerKickEvent is only called when the server sends a kick packet. In case the server goes down, BungeeCord tries to connect the player to the first priority (in our case a dummy
lobbyserver as BungeeCord won't start without a priority) with the connection reasonSERVER_DOWN_REDIRECT. We can catch this reason and provide a proper fallback inServerConnectEvent.Modification
Catch the
SERVER_DOWN_REDIRECTreason inServerConnectEventand provide a proper fallback. If no fallback is available, disconnect the player with the new disconnection reason introduced in #1399.Result
Players will be provided with a proper fallback in case of an unexpected connection close by the downstream service instead of being disconnected.
