I'm trying to connect to a VPN provided by NordVPN. I was sent a root.der certificate file and a file, bunch-of-random-numbers_tcp.ovpn, which appears to contain some credentials of some kind. If I'm not mistaken, the latter is an Open VPN file. I've used it to connect to the VPN on my linux workstation.
Let me first say the certificate file, root.der, that was sent to me appears to be for Cyber Hop, not NordVPN, and appears to be issued in the British Virgin Islands. The NordVPN cert doesn't seem much better, having been issued in Panama.
I followed the instructions here which does not make any use of the ovpn file above but does involve entering my user/password credentials. Sadly, when I attempt to connect, I get a popup window that says:
VPN Connection
User Authentication failed.
I've sniffed around a bit and see the ASUS website and the NordLayer website both recommending an app called Tunnelblick. Do we think this is safe? I don't mean to be germanophobic, but it sounds a bit weird, and today is the first I've heard of it. I find it surprising that MacOS wouldn't have some native facility to connect using an OpenVPN file.
