1. Clear the Networking caches

Run windows cmd window (click windows start menu, type 'cmd', right click on 'Command Prompt' and select "Run as Administrator").

type command below:
netsh int ip reset

then type:
netsh int ipv6 reset

then type:
netsh winsock reset

Restart your computer.

2. Reset Device Manager adaptors

Open Device Manager
Find Network Adapters
Uninstall WAN Miniport drivers (IKEv2, IP, IPv6, etc)
Click Action > Scan for hardware changes
The adapters you just uninstalled should come back

The VPN connection then works.
