Remote access SSL does not work (resets connection)

Hi 

I'm trying to setup SSL remote access using RADIUS as the back end server. I have set it up using the guide below. The problem is it tries to connect and connection resets every time. The details are provided below please help

https://www.sophos.com/en-us/medialibrary/PDFs/documentation/utm90_Remote_Access_Via_SSL_geng.pdf 

On a side note- After fiddling around with it for long I managed to get it working on one machine but it does not work anywhere else. I think one of the things I did was to export the certificate and installed it on the client machine probably that helped but the same thing does not work on other client pc's. I've tried with all the certs in the drop down. I also have a public certificate from Lucky register in case we need it. 

Thanks
