Wrong exception HttpClient when SSL certificate is expired #7629

Android application type

Android for .NET (net6.0-android, etc.)

Affected platform version

VS2022 17.4.2

Description

When doing a HTTP request with expired certificate, using HttpClient in .NET 7 Android app, the wrong exception type returned.
Expected: HttpRequestException. Returned: WebException.

Documentation of HttpClient.SendAsync indicates HttpRequestException or TaskCanceledException should be thrown.

Steps to Reproduce

var httpClient = new HttpClient();
try
{
	var request = new HttpRequestMessage(HttpMethod.Get, "https://expired.badssl.com/");
	var response = await httpClient.SendAsync(request);
}
catch(HttpRequestException ex)
{
	Console.WriteLine("SUCCESS HttpRequestMessage: " + ex);
}
catch(Exception ex)
{
	Console.WriteLine("FAIL " + ex);
}

in .NET 7 Android app using native HTTP handler.

No issues when using SocketsHttpHandler.

Expected behavior

System.Net.Http.HttpRequestException: The SSL connection could not be established, see inner exception.
 ---> System.Security.Authentication.AuthenticationException: Authentication failed, see inner exception.

Actual behavior

System.Net.WebException: Unacceptable certificate: CN=COMODO RSA Certification Authority, O=COMODO CA Limited, L=Salford, ST=Greater Manchester, C=GB
---> Javax.Net.Ssl.SSLHandshakeException: Unacceptable certificate: CN=COMODO RSA Certification Authority, O=COMODO CA Limited, L=Salford, ST=Greater Manchester, C=GB

It would be nice if the returned exception matches SocketHttpHandler by returning HttpRequestException with inner AuthenticationException and then Javax.Net.Ssl.SSLHandshakeException as inner.

Note that WebClient returns the same exception and that should keep working.

Did you find any workaround?

Simply use broader catch.
