I'm doing a MobileIron integration for an iPad app that will be distributed via MobileIron. The app uses the AppConnect SDK. This is all setup and working as expected.
Normally, network requests to production URLs work fine. They have been whitelisted for the configuration, firewalls opened, etc. However, after some time elapses (usually after about an hour of launching/re-launching) the requests start to fail. The error in iOS is specifically kCFURLErrorCannotFindHost -1003.
The only workaround is to re-install from scratch or do a force check-in. However the error comes back after a while.
The Mobile Iron app > Settings > Secure Apps > "the app" shows AppTunnel as "None". Don't know if this is important or not.
