Hi,
I'm trying to make a POST request with WebRequest on Https endpoint but this gives me exception like: System.Net.WebException "SecureChannelFailure (The authentication or decryption has failed.)"
Xamarin Mac Project's target framework is : Mono/.Net 4.5
My Application was working fine 2 days ago and i didn't make any changes but now i'm getting this error.
Any help would be much appreciated.
Thanks,
Saurav

Hi @SauravAnand Could you once validate your POST request in tools like POSTMan or Fiddler to check if the issue is with Web Service\Web API or your code at client side
@VarunBabuS thanks for quick reply. POST request is alright as i'm using this same for my Windows based product but its giving this error in Mac version of same product & same code. Before 2 days it was fine. I'm not understanding what happened suddenly.
Please show me some pointers. I have read/tried solutions available online but didn't work. I have tried like below before creating post request.
System.Net.ServicePointManager.ServerCertificateValidationCallback +=
delegate (object sender, System.Security.Cryptography.X509Certificates.X509Certificate certificate,
System.Security.Cryptography.X509Certificates.X509Chain chain,
System.Net.Security.SslPolicyErrors sslPolicyErrors)
{
return true;
};
ServicePointManager.ServerCertificateValidationCallback = MyRemoteCertificateValidationCallback;
But with NO luck.
Hi @SauravAnand If your requirement is to do a POST request could please try below code
Data that needs to be posted using below line
var PostData = JsonConvert.SerializeObject(jsonResult)
Posting the above data using below code
using (HttpClient httpClient = new HttpClient())
{
httpClient.DefaultRequestHeaders.Accept.Clear();
httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", Token);
httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage response = await httpClient.PostAsync(baseAddress, new StringContent(PostData, Encoding.UTF8, "application/json"));
meanwhile i will try to validate your code
@VarunBabuS I'm still facing the same issue. Can you please help me.
