When I'm trying to VPn into my server I'm getting the following message. Your credentials have failed for remote network authentication. I have the following ports open on both the server and router: 500, 50, 51, 1723, 1701 and 2637. My ISP does not block any of these ports. My user permissions on this server are set up to allow me acccess. I have my user name and password correct. Any thoughts?
