I’ve been helping a client distribute, successfully, a few apps via an Enterprise Developer’s account for the last few years. Recently, while doing some testing with my client’s people in the field, we’ve seen a few iOS devices (current models of iPad) having a problem with download of our app from a test server. The other testers, on similar devices, are not having this problem. On tapping the download link at the download web page the problem-people get the message: “cannot connect to [name of server].com”. Occasionally they get an iOS dialog box that offers 3 choices: “Open in App Store”, “Copy”, and “Share”. In that case, at the top of the dialog box we see: itms-services://?action=download-manifest&url=https://servername.com/EZT.plist which is the correct construction (forgive me for concealing the actual server name.
Again, most of the rest of us attempting download of the exact same ipa file via the same server are having no difficulty. In one case, at least, we’ve tried clearing the Safari cache without better results. Of course the credentials are in good shape: the html file and manifest file, as well as the app's certificate and provisioniong profile. Any ideas? Thanks.
