Cookie insert troubles

Yeah I have a VS for ports 80 and 443 however what I am seeing is this. If I put the cert for the application via an SSL profile on and the generic SSLServer profile on, connections get reset immediately. If I do the same thing but instead put the server-ssl-insecurecompatible profile on in place of the generic SSLServer profile on then all works fine. Taking a packet capture seems to suggest that between the client and the VS, traffic get's encrypted but between the VS and the web servers, the web servers are refusing to encrypt traffic and I can see data in plain text.
