question

Hi team, so im creating this app using Foursquare's Places API, everything seems good, but im not able to get the values from the API to the JSon variable, since when debbugin the app shows the attached error on the line before the Json (Line 23)

"The SSL connection could not be established, see inner exception"

Inner Exception says the following:

"Ssl error:1000007d:SSL routines:OPENSSL_internal:CERTIFICATE_VERIFY_FAILED
at /Users/builder/jenkins/workspace/archive-mono/2020-02/android/release/external/boringssl/ssl/handshake_client.c:1132"

I've tried using the next line of code on top of the method

  ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, sslPolicyErrors) => true;

I've also tried:

 client.RemoteCertificateValidationCallback = (sender, certificate, chain, sslPolicyErrors) => true;

But this last one is not recognizng the RemoteCertificateValidationCallback method, can some one please help ? Here's the code im using for the client

  ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, sslPolicyErrors) => true;
    
    
    
    
             List<Result> venues = new List<Result>();
    
             var url = VenueRoot.GenerateUrl(Latitude, Longitude);
    
                
             RestClient client = new RestClient(url);
              
               
    
             var request = new RestRequest(Method.Get.ToString());
    
         
    
             request.AddHeader("Accept", "application/json");
    
             request.AddHeader("Authorization", Constants.HEADER);
    
             RestResponse response = await client.ExecuteAsync(request);
    
             var json = response.Content.ToString();

         ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, sslPolicyErrors) => true;




         List<Result> venues = new List<Result>();

         var url = VenueRoot.GenerateUrl(Latitude, Longitude);

       using (HttpClient Client = new HttpClient())
             {
                 try
                 {
                     var Response = await Client.GetAsync(url);
                     Client.DefaultRequestHeaders.Add("Accept", "application/json");
                     Client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Authorization", Constants.HEADER);

                     var Json = await Response.Content.ReadAsStringAsync();
                     var venueRoot = JsonConvert.DeserializeObject<Venue>(Json);

                     venues = venueRoot.Results as List<Result>;

                 }
                 catch (Exception e)
                 {
                     var CatchException = e.ToString();

                 }


             }
           
         
         return venues;
