I just tried setting it up fresh and it failed. After some troubleshooting, for me the issue was it did not import the cipher configuration for the server... 👀
So goto the imported VPN connections settings -> VPN (openvpn) tab -> advanced button on the bottom right ->security tab -> set cipher manually from the drop down list.
For me the contents of the Austria.ovpn file contained the line cipher aes-128-cbc
so that is what I set it to. After that it connected fine. Should probably set HMAC too if its blank for me that would be sha1
