title: Django app not working on mobile only (desktop is fine)?
body: <p>I'm running a Django app on a private intranet which requires either the company wifi to access or, alternatively, a VPN connection in order to open it from a non-company wifi channel. That's working as intended.</p>
  
  <p>The issue is that I can access the site from mobile (iPhone, iPad) when I'm on the company wifi. But when I'm connected through public wifi, <em>even if I'm connected via VPN and I can access the intranet</em>, I cannot access the site.</p>
  
  <p>For a variety of security reasons I can't disclose precise details or code, so I'm not looking for an explicit solution. Instead, I would be very, very grateful for some general ideas as to what might possibly be causing this, or things that I could start looking into and/or check.</p>
  
  <p>I know this isn't your typical stack overflow post, but it is definitely useful for me and I believe helpful to anybody else who runs into a similar issue if we can create a list of possible reasons for this error. </p>
