The connection is down or something is blocking it

I activated the USB Tethering, but when i try to connect my phone to my PC with USB, my phone says, first : Beware, there is no active connection, and then : can’t connect, the connection is down or something is blocking it

Hello,

Please try this, it’s from a thread where someone had a similar issue:

Does it work if you temporarily disable the Windows firewall?

If so:

  • Re-enable the firewall
  • Click on the check firewall button in the server
  • Click on restart
  • Click on the apply button
  • Try to connect the Android app
