Error 12175 calling WINHTTP_CALLBACK_STATUS_REQUEST_ERROR, 'A security error occurred

In local working fine.

But on IIS server we got error :

"Error 12175 calling WINHTTP_CALLBACK_STATUS_REQUEST_ERROR, 'A security error occurred

What version of .NET Core are you running? Does the same thing happen when using HttpClientHandler or SocketHttpHandler, instead of WinHttpHandler?

And lastly, if it's repeatable and you can whittle it down to a small repro, that'd be awesome.

.NET Core 2.2 @scalablecory

Triage: This error usually means something is wrong with certificate, or TLS connection.
Right now it is not actionable -- we would need a repro - ideally console app against the URL in the picture above.
Also, please try to run the repro with SocketsHttpHandler as asked above.

Closing for now, feel free to reopen one it is actionable (aka repro is available). Thanks!

This sometimes happens in our test runs eg

This observation may not help, but I figured I'd reuse this bug for it.
