When TCP connection fails (e.g. no network during IDLE reconnect), NIO's HappyEyeballsConnector can be deallocated with unfulfilled internal promises, triggering a fatal assertion in debug builds (EventLoopFuture.deinit). Bypass the connector entirely by resolving DNS up-front with SocketAddress.makeAddressResolvingHost() and using bootstrap.connect(to:) instead of bootstrap.connect(host:port:).
