Getting sometime error like:

System.IO.IOException: Received an unexpected EOF or 0 bytes from the transport stream.

Here is failing:

const SslProtocols sslProtocol = SslProtocols.Tls12;
var task = _sslStream.AuthenticateAsClientAsync(targetHost, _defaultClientCertificates, sslProtocol, _checkCertificateRevocation);
task.Wait();

The System.IO.IOException: Received an unexpected EOF or 0 bytes from the transport stream error message typically occurs when you are trying to read from a stream and the stream ends before you have received all the data that you expected. This error message could occur in this code if the SSL authentication process fails, or if there is a problem with the SSL connection after authentication.

There are several things you can try to resolve this issue:

Check the target host name: Make sure that the target host name specified in the targetHost parameter is correct. If the host name is incorrect, the SSL connection will not be established.
Check the SSL protocol: Make sure that the SSL protocol specified in the sslProtocol parameter is supported by the server you are connecting to. You may need to try different SSL protocols to see which one works best with your server.
Check certificate revocation: If the _checkCertificateRevocation parameter is set to true, make sure that the server's certificate revocation list (CRL) is accessible and up-to-date. If the CRL is not accessible or is out-of-date, the certificate validation process may fail, causing the exception.
Check the client certificates: Make sure that the client certificates specified in the _defaultClientCertificates parameter are valid and have not expired. If the client certificates are invalid or have expired, the SSL authentication process may fail, causing the exception.
