Hello, I installed a clean version of WireGuard and am using it on my phone, but I've encountered a problem. The handshake works fine when I enable the tunnel through the app. However, traffic doesn't start afterward. If I switch networks (for example, turn on airplane mode for a few seconds and then turn it off), traffic starts working fine. What could be causing this problem?

  • WirelessGuard? Are you joking? 

    What is your phone brand/model, OS and version?

    And, are you using a personal VPS or a commercial VPN?
