Hello!

The following network interface:
2022.09.10 16:15:52 - Using WinTun network interface "VPN - VPN Client (VPN Client Adapter - VPN)"

is causing a critical error to OpenVPN:
2022.09.10 16:15:58 - OpenVPN > There are no TAP-Windows nor Wintun adapters on this system.  You should be able to create an adapter by using tapctl.exe utility.
2022.09.10 16:15:58 - OpenVPN > Exiting due to fatal error

You should be able to resolve the problem in the following way:

• please select Settings > Networking
• enter "Eddie" (without quotes) in the VPN interface name field (see also https://www.clodo.it/host/images/f625221af86ac02e33238f0aaaffca81bae26bbf.png )
• click "Save" and test again a connection

Alternatively, you can remove that problematic network interface. As a further option, you can connect with WireGuard. To do so, please select Settings > Protocols and pick WireGuard. (WireGuard will not use the interface detected by Eddie for OpenVPN).

Kind regards
