Hello!
It's a bug in the Configuration Generator coming from the times when the name earth3.airvpn.org existed. Now it doesn't exist anymore. Please modify it into earth3.vpn.airdns.org or earth3.all.vpn.airdns.org. The first name resolves into the entry-IP address 3 of the "best" Earth server, the latter into entry-IP addresses 3 of all VPN servers.
We will fix the bug, in the meantime you can simply edit with any text editor your ovpn file. Thank you for having found and pointed the bug out.
Kind regards
