在本地网络上执行GET请求时出现错误1009

Question

本地服务器上的URLSession错误-1009

我需要使用HTTPS协议从硬件设备中获取数据。设备的IP地址为 192.168.4.1 ，当我使用该设备的设备连接到计算机上的热点时，便在Postman上调用GET请求https://192.168.4.1/scanlist，作为响应返回JSON数据。但是，当我使用iPhone连接设备热点并且尝试在iPhone上执行相同的GET请求时，出现URLSession错误-1009。

guard let url = URL(string: "https://192.168.4.1/scanlist") else {return}
    let task = URLSession.shared.dataTask(with: url) { (data, response, error) in
        guard let dataResponse = data,
            error == nil else {
                print(error?.localizedDescription ?? "Response Error")
                return }
        do{
            //here dataResponse received from a network request
            let jsonResponse = try JSONSerialization.jsonObject(with:
                dataResponse, options: [])
            print(jsonResponse) //Response result
            guard let jsonArray = jsonResponse as? [ScanList] else {
                return
            }
            for dic in jsonArray{
                self.ssidListArr.append(dic)
            }
            if self.ssidListArr.count > 0{
                self.popUpView.isHidden = false
                // populate tableview
            }
        } catch let parsingError {
            print("Error", parsingError)
        }
    }
    task.resume()

我遇到错误：

Error Domain = NSURLErrorDomain代码= -1009“ Internet连接似乎已脱机。
