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!

Hi,

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 - https://learn.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-troubleshoot-vpn-point-to-site-connection-problems

Hope this helps.
