Using SSL certificate with Fleck Websockets

I get this error when pointing Fleck to my OpenSsl certificate, or cloudflare certificate

Failed to Authenticate System.AggregateException: One or more errors occurred. ---> System.Security.Authentication.AuthenticationException: A call to SSPI failed, see inner exception. ---> System.ComponentModel.Win32Exception: An unknown error occurred while processing the certificate
   --- End of inner exception stack trace ---

   at System.Threading.Tasks.TaskFactory`1.FromAsyncCoreLogic(IAsyncResult iar, Func`2 endFunction, Action`1 endAction, Task`1 promise, Boolean requiresSynchronization)
   --- End of inner exception stack trace ---

What does this mean, and how do I fix it? Thanks.

This generally means that the client is using an SSL protocol which is different than the server. You can specify the SSL protocol to support on the server by:

WebSocketServer ws = new WebSocketServer(wsUri)
{
EnabledSslProtocols = System.Security.Authentication.SslProtocols.Tls12
};
