title: Co-Turn server not working properly for Web RTC project
body: <p>I have a turn server which is using co-turn and hosted on GCP. </p>
  
  <p>And already installed the server successfully without any error and enabled the port. </p>
  
  <p>But when I used it back on my web rtc project, it seems like it's not working because my application only works only on the same router or network. </p>
  
  <p>It's not working on a different network. </p>
  
  <p>I tried checking on <a href="https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/" rel="noreferrer">https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/</a> and get the following result which says it is fine. </p>
  
  <p>So, i'm a bit lost about where to check anymore. </p>
  
  <p>Please kindly help me what I can check anywhere else. Thanks. </p>

  <h2>Latest Update</h2>
  
  <p>When I debug on chrome://webrtc-internals/, there is an error message on icecandidateerror event which state as Unauthorized.</p>
  
  <pre><code>url: turn:turn.xxxxx.live:5349?transport=udp
  address: 10.19.95.x
  port: 41207
  host_candidate: 10.19.95.x:41207
  error_text: Unauthorized
  error_code: 401
  </code></pre>
  
  <p>When I recheck the turn server which I created with reference to <a href="https://ourcodeworld.com/articles/read/1175/how-to-create-and-configure-your-own-stun-turn-server-with-coturn-in-ubuntu-18-04" rel="noreferrer">this link</a>, I still have user=guest:somepassword line, so trying my server with that password to confirm if it is the user issue.</p>
  
  <p>Still no luck though. Please help me guide where did I need to look more into. </p>
  
  <p>Since I'm new to this technology and infrastructure, I'm a bit lost here. </p>
