  <p>I referred this link: <a href="https://stackoverflow.com/questions/60635880/tunnel-url-not-found-falled-back-to-lan-url">Tunnel URL not found, falled back to LAN URL</a>
  But it is of no help to me. And I made sure the network I am using in the laptop and the mobile is the same. Still I am getting this error. What is the resolution to this problem.</p>
