Solved
This problem is seen at OpenVPN client. It happens very often that the TUN/TAP adapter is not started and OpenVPN is unable to setup IPs and routes.
You have to set your Tap Adapter to “always connected”
To do this do the following steps:
- Go into device manager
- Find your Tap Adapter
- Right click
- Select “Propterties”
- Select “Advanced Media Status”
- Set it to “Always Connected”
- Click Ok
- Restart computer.
Successfully used this on both Windows Server 2012 R2 and Windows 8.1
