I'm trying to consume a REST API, and this API need an https connection. But i'm stuck on this Error:

  • System.Net.Http.HttpRequestException: 'The SSL connection could not be established, see inner exception.

which, due to the certificate's untrust or something similar, throw the previous exception.

Is there a way to bypass the certificate and get the response?

How to bypass invalid SSL certificate.

You can bypass the certificate check, and solve this error, by override the certificate check on the callback function on the HttpClientHandler like the below code.

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

using(var httpClient = new HttpClient(clientHandler))
{
 // your code
}
If you don’t ask, the answer is always NO!
