I'm running Sierra and trying to connect to VPN network using a certificate. When I press the Connect button I get an error:
An unexpected error occurred. Try reconnecting. If the problem continues, verify your settings and contact your Administrator.
I wonder where I can see the logs of connection attempt because the error message is not clear at all. I saw some advices on the internet about checking
/var/log/system.log, but there is nothing related to VPN on my machine. Maybe I should somehow enable DEBUG logging?
