I want to fetch and pass the imported SSL certificate as trusted while connecting to the web socket in c#. Currently I am using websocketclient but getting the SSL Certificate Exception even after importing. I need to fetch it and connect to server related to handshaking.

The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.

What I have tried:

Currently Connecting as
connect("wss://10.34.1.1/Test.aspx/) ;

webSocket.ConnectAsync(new Uri(uri), CancellationToken.None);
