Anyconnect disconnects client after clicking on "accept".

[cavazos.art]

Anyconnect disconnects client after clicking on "accept". Our vendor is using Windows Server 2012 R2.

We see that the client passes authentication and connects then promptly disconnects without establishing a session.

The version of Anyconnect is  4.2.01035

Hi cavazos,

You can see that windows server OS is not officially supported / tested platform for anyconnect:-

You can still install the anyconnect diagnostic tool DART and then check for the errors on the logs.

You could probably run "debug webvpn anyconnect 255" to check the logs to see where the connection is failing
