WireGuard VPNUnlimited

On the Gl-iNet pages it shows that VPNUnlimited can be used with the WireGuard protocol.
However, when I press the link on the Gl-iNet page, it says 404 page not found.
Any help?

Gl-iNet page:

Page that can not be found:

You need to contact VPNUnlimited and ask them why the help page was removed, maybe they no longer support Wireguard.

It is there!

Thanks alzhao,
The page seams to be back online. Will try it when I’m home.
