func getTCPConnection(host: String, port: String, enableTLS: Bool) async throws -> NWTCPConnection? { let endpoint = NWHostEndpoint(hostname: host, port: port) // let enableTLS = true let connection = createTCPConnectionThroughTunnel(to: endpoint, enableTLS: enableTLS, tlsParameters: nil, delegate: self) var count = 0 while connection.state != .connected { count += 1 try await Task.sleep(nanoseconds: 0_500_000_000) if connection.state == .connected { return connection } if connection.state == .disconnected { self.flushLog("Connection state => disconnected. throw error") throw StateMonitoringError.connectionDisconnected } if count > 30 { self.flushLog("Connection time out") if let error = connection.error { self.flushLog("\(error)") } return nil } } return nil } Previously, this function worked perfectly. However, when OnDemand Rules are set to true and the device is left idle for a long time (such as in Low Power Mode or with no activity), executing this function during the automatic reconnection process results in a connection timeout, because the connection takes too long to be established.
