title: Ngrok session expired (raspberry project)
body: <p>I've made a server on my raspberry and a mobile app to control it. I can connect to it when my mobile is connected to the same net, but I cannot do it outside of the net. </p>
  
  <p>Actually I'm using ngrok to reach it but the session expires in 8 hours.</p>
  
  <p>Is there any way to keep it on all the time I want? (or kind of, like a script that auto execute ngrok if the system detects that is not running)</p>
  
  <p>And without ngrok how could I reach that server?</p>
