The symptoms are as follows: you select a VPN connection in the system tray and click “Connect”. The “connecting” status goes on indefinitely without ever establishing a successful connection. The connection attempt is silently closed, and after you reopen the system tray you’re again offered the “Connect” option.

How to make it works:

• Click on Windows icon

.

• Type VPN then click on VPN Settings
  

• Then select the VPN and click Connect
