Certificate Error in Workstation.ConsoleApp and also in Workstation.DataLoggingConsole about opc-ua-samples

Look in program.cs and you will find:

             Console.WriteLine("Step 4 - Create a session with your server.");
            var session = new UaTcpSessionChannel(
                appDescription,
                new DirectoryStore(Environment.ExpandEnvironmentVariables(@"%LOCALAPPDATA%\Workstation.ConsoleApp\pki")),
                userIdentity,
                remoteEndpoint);

With explorer you can browse to this directory:
%LOCALAPPDATA%\Workstation.ConsoleApp\pki

Open the "\own" directory and you will find the "client.crt". If you open the "crt" file it will display "Valid from x to y." If the dates are wrong you can delete the "client.crt" and the program will create a new cert on the next run..
