What kind of IDIOTIC answer is that?
If you have nothing to say, better say nothing.
Server 2019 RRAS AlwaysON VPN, using certificate, working fine with Windows clients, MacOS clients, but NOT iOS
No matter what I configure with Apple Configurator 2 I always get:
CoId={5F663023-EC52-FA99-4E03-5F2E41939CC8}: The user ******@domain.com connected from xx.xx.xx.xx but failed an authentication attempt due to the following reason: The connection was prevented because of a policy configured on your RAS/VPN server. Specifically, the authentication method used by the server to verify your username and password may not match the authentication method configured in your connection profile. Please contact the Administrator of the RAS server and notify them of this error.
CoId={5F663023-EC52-FA99-4E03-5F2E41939CC8}: The following error occurred in the Point to Point Protocol module on port: VPN2-163, UserName: <Unauthenticated User>. The connection was prevented because of a policy configured on your RAS/VPN server. Specifically, the authentication method used by the server to verify your username and password may not match the authentication method configured in your connection profile. Please contact the Administrator of the RAS server and notify them of this error.
Any help appreciated
