    Thanks for posting in Q&A platform.

    Before we go further, I would like to confirm the following information with you:

    1. What's the type of VPN connection? PPTP, L2TP, SSTP or IKEv2?
    2. Is there any error message? Please provide the screenshot of error message for further troubleshooting.

    Best Regards,

    The connection I typically use is SSTP but none will work the error message I receive on the server is ID 20255 the description is as follows

    CoId={5C927C70-558C-42BE-BCA5-246DCE82BC74}: The following error occurred in the Point to Point Protocol module on port: VPN1-49, UserName: (Name). The connection could not be established because the authentication method used by your connection profile is not permitted for use by an access policy configured on the RAS/VPN server. Specifically, this could be due to configuration differences between the authentication method selected on the RAS/VPN server and the access policy configured for it.
