We're using HttpWebRequest to hit HTTPS urls, on iOS. In Debug, local builds, etc. everything works fine. The HTTPS urls we're hitting have valid, commercially signed, perfectly normal certificates, everything checks out there. All is well.
The app was submitted and approved by Apple. But the version with the official Seal of Approval from iTunes is unable to hit any HTTPS urls - we aren't seeing any exceptions, problems with JIT; the request appears to be sent [but isn't] and we timeout waiting for a response.
Note that the problem is ONLY with the Apple-release build, all our builds work fine.
Anybody seen anything like this before?
Thanks!
Does Unity.WWW work with HTTPS? What is WWW that HttpWebRequest doesn't have?
I'm also encountering this using the 'WebClient' class.. Appearntly it's a bug in Unity's Mono. I tried using the BestHTTP plugin but encountered other problems as well. Did you have any progress with this?
We ended up using Unity.WWW to get both HTTP and HTTPS working on Apple release builds.
Use http instead of https in the urls and that should work fine for you.
Apple blocks access to HTTPS through non-approved code paths, and HttpWebRequest is not part of the approved code path. We switched our implementation around and used Unity.WWW to get around the problem.
Hi trasa, I encountered a different problem, WebClient fails because of one of it's properties being reflected (and reflection is not permitted on a Unity iOS build). I needed Download buffering and WWW does not support it so I'm using BestHTTP, which works great.
