Connect to server with specific security level

[nicki004]

Hello,

I'm not able to connect to a server with any security policy except "None".

Even the Demo Server and Full Client don't work.
(I right clicked every connection and clicked "Trust permanently")

I also tried to connect to the EndpointUrl with SecuritySelection.BestAvailable with the same result.

"BadCertificateUntrusted"

Is someone able to provide an easy example for a client or am I missing something?

Thanks
