我使用的 HTTP 库是否与 Windows 7 不兼容？

问题描述

我有一个类，我用它来创建 HTTP 客户端的实例，以对任何所需的 API 执行 Get 操作。现在，当我在装有 Windows 7 的机器上使用它时，它在 Windows 10 中运行顺畅，它给我一条通用消息“发送请求时发生错误”。我是跳过了流程中的任何步骤还是兼容性/网络问题？

这是我的类代码

   public static class HttpService
    {

        private static readonly HttpClient _httpClient;
        static HttpService()
        {
            
            _httpClient = new HttpClient();
        }
        public static async Task<string> ExecuteGetStringAsync(string endpoint)
        {
            string res = string.Empty;
            
           
            HttpResponseMessage response = await _httpClient.GetAsync(endpoint);
            
            // Handle the response
            switch (response.StatusCode)
            {
                case HttpStatusCode.OK:
                    res = await response.Content.ReadAsstringAsync();
                    _httpClient.DefaultRequestHeaders.ConnectionClose = true;
                    break;
                case HttpStatusCode.NotFound:
                    await _logger.Error($"StatusCode: {HttpStatusCode.NotFound},Response: {res}");
                    throw new HttpException(404,"Not Found");
                case HttpStatusCode.InternalServerError:
                    res = await response.Content.ReadAsstringAsync();
                    await _logger.Error($"StatusCode: {HttpStatusCode.InternalServerError},Response: {res}");
                    throw new HttpException(501,$"ExecuteGet->Failed: {res}");
                case HttpStatusCode.Unauthorized:
                    await _logger.Error($"StatusCode: {HttpStatusCode.Unauthorized},Response: {res}");
                    throw new HttpException(401,"Unauthorized access");
                default:
                    int statusCode = (int)response.StatusCode;
                    await _logger.Error($"StatusCode: {statusCode},Response: {res}");
                    throw new HttpException(statusCode,response.ReasonPhrase);

            }
            
            return res;
        }
    }
}

我正在使用该方法使用我使用 serverIp 构建的 API 连接服务器

private static async Task ConnectToServer(string serverIp)
        {
            string releaseUrl = string.Format("https://{0}/bin/APILinks?cmd=connectToServer",serverIp);
            try
            {
                await HttpService.ExecuteGetStringAsync(releaseUrl);
            }
            catch (Exception ex)
            {
                await _logger.Error($",serverIp: {serverIp},cookie: {cookie},error: {ex.Message},stacktrace: {ex.StackTrace}");
            }
        }

添加我在日志中得到的错误和堆栈跟踪：
