[WireGuard] config file works on iOS app but not on Mac app (wireguard-apple)

[Yuchen Lin]

Hi, Wireguard development team members,

How is your day so far?

This is Yuchen Lin and I am currently working on a project based on
your open-source project wireguard-apple.

The code is well structured, easy to understand, and works really
well, except for one issue. When I was trying to connect to an actual
network with a config file, the iOS app I built works fine. But on the
macOS App, the config file could not be activated and giving me the
error saying I need to make sure I am connected to the internet, which
I am certain it is connected.

I am on the latest commit for 12-07-2020 (UI: macOS: Fix UTF-8 and
UTF-16 conversions in highlighter code 9269c7c Andrej Mihajlov
<and at mullvad.net> Dec 17, 2020 at 8:36 AM). Is there any possibility
that you might know which direction I should digger deeper to solve
this issue?

The following log is the log when the fail activation happens.

Any help would be really appreciated.
Thanks,
