Hello everyone.

I was using the built-in VPN just fine yesterday. And when i woke up today and tried to connect to it, i get this error now.

Any help would be greatly appreciated!

    Can you check your system time is in sync and not out of sync? check the system tray and date/time should be as per your timezone. Also check the keys are valid and local certificates on the system are not expired, check the troubleshooting steps over here -

    Hope this helps.
