The SSL connection could not be established

Question

I am using a third party library (Splunk c# SDK ) in my ASP.NET core application. I am trying to connect to my localhost Splunk service via this SDK, but I get an exception

Answer 1

ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, errors) =>
{
    // local dev, just approve all certs
    if (development) return true;
    return errors == SslPolicyErrors.None ;
};

Answer 2

Yes, you can Bypass the certificate using below code...

HttpClientHandler clientHandler = new HttpClientHandler();
clientHandler.ServerCertificateCustomValidationCallback = (sender, cert, chain, sslPolicyErrors) => { return true; };

// Pass the handler to httpclient(from you are calling api)
HttpClient client = new HttpClient(clientHandler)

Answer 3

This worked for me,

Create a Splunk.Client.Context by providing custom HttpClientHandler, that will bypass SSL invalid cert errors.

HttpClientHandler handler = new HttpClientHandler();
handler.ServerCertificateCustomValidationCallback = (sender, cert, chain, sslPolicyErrors) => { return true; };

// Create Context 
Context context = new Context(Scheme.Https, "localhost", 8089, default(TimeSpan), handler);

// Create Service
service = new Service(context);
