On my client when attempting to authenticate an SSL connection, an exception of type AuthenticationException is raised. The errors found in the certificate are RemoteCertificateNameMismatch and RemoteCertificateChainErrors .
The code used to authenticate:
sslStream.AuthenticateAsClient(serverName);
How can I resolve this exception?
Let's break the problem into parts.
Regarding the error RemoteCertificateNameMismatch , this is due to the fact that the name that must pass AuthenticateAsClient(...) is the name of the server. That is, if the server is localhost , you should pass that name this way:
sslStream.AuthenticateAsClient("localhost");
If you are generating your own certificate, you must ensure that the name that passes to AuthenticateAsClient is the same as that in the "CN = [server name]" option.
For RemoteCertificateChainErrors , if you are generating your own certificate, the algorithm that validates the certificate may not trust your certificate because it is not in a secure location.
One way to resolve the problem is to install the certificate in the certificate store of your computer or use the following code (source:
