title: ngrok speed became slow
body: <p>Ive been using <a href="https://ngrok.com/" rel="noreferrer">ngrok</a> to test an app on my phone, with react-native for the past 2 weeks.  And so far its been pretty decent and quick.  </p>
  
  <p>Until today.
  Now it suddenly takes about 50 seconds for a request to make a roundtrip from my phone, to my localhost and back.  Or from my browser, to the ngrok tunnel, back to my localhost.</p>
  
  <p>At first I thought, ok ngrok is either down or experiencing slowdowns. But then I decided to hit it with Postman, and with that the request is fast.  Around 0.5 seconds.  Same when I access the tunnel stats.  A replay request is like 1second. </p>
  
  <p>Just when I do it over my phone, or browser its now extremely slow.
  Is there any specific reason this may suddenly be occuring?
  Can anyone shed any light on where I should even begin looking?</p>
  
  <p>I've tried rebooting, and flushing DNS, to no avail.</p>
