It's an Eddie bug which checks IPv6 routing even when IPv6 routes are not pushed (our servers do not push IPv6 routes to OpenVPN versions older than 2.4 because such versions had various issues with IPv6).
The bug is resolved in Eddie 2.17beta. If you don't feel like testing a beta version, the quick ,alternative workarounds are:
- open "Preferences" > "Networking" from Eddie main window
- set "IPv6 Layer" to "Block"
- click "Save"
- upgrade to OpenVPN 2.4.x and don't touch Eddie IPv6 layer configuration.
Solution "2." is recommended because it allows you to use IPv6 from AirVPN servers.
