After installing Ark Steam on a Windows system (I use mac osx), it *still* would not connect. So ...
I tried connecting using a proxy, a VPN service. And I connected with no problem (see attached screenshot).
So, doesn't this mean that there is a server-side filter or "blacklist" of some kind that is preventing my real IP address from connecting?
My friend and I have been playing on our MacBooks on the Nitrado server since April, and now *neither* of our computers can connect, nor can a Windows system running on my wifi.
