TCP server with SSL works on .NET 4.8 - but on .NET8 not?

[sveni2211]

Hi.

I have a TCP server with a self signed certificate in a project running. This works on .NET 4.8.
Now i try to switch it to .NET8 (also tried 10) to use it on linux, too. But with the same code and the same certificate i get an error. I don't understand this. The error message itself does not explain something: Authentication failed, see inner exception. The inner exception is localized, in original it's "Beim Verarbeiten des Zertifikats ist ein unbekannter Fehler aufgetreten." (means, there is a unknown error on processing certificate). Because it's localized i think it's from windows system or .NET itself.
I think the problem comes from the SSLStream class. But i have no idea to resolve it. Any sugestions?

Hi @sveni2211 sorry for the delay in getting back to you, you should be able to load the certificate yourself using X509KeyStorageFlags.

  var cert = new X509Certificate2(pfxFile, password, X509KeyStorageFlags.Exportable | X509KeyStorageFlags.MachineKeySet);
  var server = new WatsonTcpServer(ip, port, cert, TlsVersion.Tls12);

I'm applying a fix now that uses a default for these values and will update NuGet accordingly.
