Authentication is already in progress.
This object has been closed.
The AuthenticateAsServer method is not supported on Windows 95, Windows 98, or Windows Millennium.
This method authenticates using the SslProtocols value set to Default. This value specifies that either Secure Sockets Layer (SSL) 3.0 or Transport Layer Security (TLS) 1.0 are acceptable for secure communications. TLS 1.1 or TLS 1.2 will not be used even if those protocols are enabled on local computer. The certificate revocation list is not checked during authentication. The client is not required to provide a certificate for authentication.
This method blocks until the operation completes. To prevent blocking until the operation completes, use one of the BeginAuthenticateAsServer method overloads.
If the authentication fails, you receive a AuthenticationException, and this SslStream is no longer useable. You should close this object and remove all references to it so that it can be collected by the garbage collector.
