Hi There,
I have a project with Asp.Net Core 3.1. On the Login page when click Submit button I will call an API to help validate the account as below:
public async Task<ApiResult<string>> Authenticate(LoginRequest request)
{
var json = JsonConvert.SerializeObject(request);
var httpContent = new StringContent(json, Encoding.UTF8, "application/json");
var client = _httpClientFactory.CreateClient();
client.BaseAddress = new Uri(_configuration["BaseAddress"]); // = https://localhost:44387
var response = await client.PostAsync("/api/users/authenticate", httpContent);
if (response.IsSuccessStatusCode)
{
return JsonConvert.DeserializeObject<ApiSuccessResult<string>>(await response.Content.ReadAsStringAsync());
}
return JsonConvert.DeserializeObject<ApiErrorResult<string>>(await response.Content.ReadAsStringAsync());
}
But I got an error System.Net.Http.HttpRequestException: The SSL connection could not be established, see inner exception.
System.Net.Http.HttpRequestException: The SSL connection could not be established, see inner exception.
---> System.Security.Authentication.AuthenticationException: Authentication failed because the remote party sent a TLS alert: 'HandshakeFailure'.
---> System.ComponentModel.Win32Exception (0x80090326): The message received was unexpected or badly formatted.

I not sure but maybe you have to self-trust SSL for your web API.
To self-trust SSL you can add code below inside constructor of the class contains method call API.
//// IMPORT LIBS using System.Net; using System.Net.Http; using System.Net.Http.Headers; using System.Net.Security; using System.Security.Cryptography.X509Certificates; ////////////// ServicePointManager.ServerCertificateValidationCallback = delegate (object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { return true; };This code will auto return true when validating SSL for you.
I hope it useful for you.

You have to sure all sites you are using HTTPS and SSL are working fine.
If SSL not working you need to install a certificate for it by using the command below: (Run cmd with admin)
dotnet dev-certs https --trustI hope it useful.
