尝试以其访问权限禁止的方式访问套接字-部署到Azure之后

如何解决尝试以其访问权限禁止的方式访问套接字-部署到Azure之后

在端口“ 81”处，我在任何地方的控制室都具有自动化功能，并且希望进行api调用以获取身份验证令牌。我在下面的本地代码中尝试了其正常工作，但是当我在azure应用程序服务中部署时却出现错误

              using (HttpClient httpClient = new HttpClient())
                   {                     
                       var authenticateClient = new RestClient("ipaddress:81/v1/authentication");
                       var authenticateRequest = new RestRequest(Method.POST);
                       authenticateRequest.AddHeader("Content-Type",AAConstant.fileFormat);

                       authenticateRequest.Parameters.Clear();

                       authenticateRequest.AddJsonBody(new
                       {
                           username = "******",password = "*******"
                       });
                       IRestResponse authenticateResponse = authenticateClient.Execute(authenticateRequest);

更改了天蓝色的应用程序服务计划，并禁用了防病毒，防火墙，但无效。

任何帮助！
