Do watchOS apps support IP request communication within a local area network?

As a third-party application on Apple Watch, can it be located in the same LAN httpServer? Currently, when testing to initiate an http request in the LAN, the connection timeout is returned, code: -1001

self.customSession.request("http://10.15.48.191:9000/hello").response { response in
                        switch response.result {
                        case .success(let data):
                            dlog("✅ 请求成功，收到数据：")
                            if let html = String(data: data ?? Data(), encoding: .utf8) {
                                dlog(html)
                            }
                            
                        case .failure(let error):
                            dlog("❌ 请求失败：\(error.localizedDescription)")
                        }
                    }

执行后报错
