title: Can't use adb when connected to VPN
body: <p>My PC and Android TV device are in the same net section,so I can use <em>adb</em> connect the debugging device.Also ,I use <strong>adb devices</strong> command,it shows device on work.But when My PC and device use the same vpn based on the previous internet,I try to ping the device IP,it worked,then I use adb connect the device,it shows connect,but when input <strong>adb devices</strong> command , it shows <strong>device offline</strong>. I'm sure the error can't be  caused by adb version,for it can work when disconnect the vpn.who can help me? I'm very appreciate for that.</p>
