As another test using Windows with Wireguard:
- Wireguard: connects.
- Opening WSL, then doing dig AAAA app-name.internal: works
- Opening cmd.exe (NOT wsl) and pinging the ipv6 address: works
- Attempting to connect via DataGrip using app-name.internal: nope
- Attempting to connect via DataGrip using the ipv6 address: works
Would definitely like to be able to use the app-name to connect as it leads to quite a bit of wondering if Wireguard is working at all and general confusion!
