Background Information: WSL Version: 2.1.5.0 Windows Version: 10.0.22631.3447 My Workarounds: I created a file named .wslconfig in the directory C:\Users\%USERPROFILE%\ and added the following lines: [experimental] autoProxy=true dnsTunneling=true networkingMode=mirrored This configuration is necessary because DNS calls to the Windows host are blocked. For more detailed information, please visit this link. After adding these experimental features, my VPN connected successfully. Hope these workarounds are helpful for anyone experiencing similar issues.
