ios 9 in house app unable to install

We are having exactly same problem with our enterprise app. Could you please update with status of yout ticket with Apple?

Yep, Preferences:General:Profiles then trust the signing identity

Issue is occuring again. Several reports...

Same here. All enterprise apps (regardless of whether they're being installed by MDM or not) are showing untrusted enterprise developer. If it is on an unmanaged iOS device and the user goes into settings>general>profiles and approves the trust the error then says there is no network connection.

We are unable to resolve the ppq.apple.com site internally or externally, so I have a feeling this is a widespread issue.

Anyway of reporting to Apple? I'm having same issue.

We are also experiencing the same issue with verifying enterprise developer profiles on iOS 9. I think the problems started sometimes around 12pm east coast time and are still occuring as of 3:45PM east cost time.

Also having the same issue. Spent a few hours on the phone with Apple support with no resolution. We've tried on multiple devices, both on wifi and LTE connections. I believe it's an Apple issue, but they can't confirm or deny that.

Yes, our company has escalated it to AppleCare as high priority and it has been received and responded to by Apple. They confirmed ppq is not responding to verification requests and they are working to resolve. System status (https://developer.apple.com/system-status/) is still showing green though for "Certificates, Identifiers and Profiles" which is causing me to lose a bit of faith in that site.

We're definitely seeing it in our Enterprise apps.

I believe that entry in system status is only to indicate that the ability to create/manage certificates is available or not. I don't think it has any bearing on whether the trust server is available.

Still experiencing this issue. Been experiencing this since 2pm EST. Has anyone gotten in contact with Apple, and found out what the issue is?

Same issue. All updated Enterprise Apps are "Unable to verify <ENTERPRISE DEVELOPER> Apps --- A network connection is required to verify <ENTERPRISE DEVELOPER> apps on this iPhone. Connect to the internet and try again."

I don't think this is a build number problem; it is happening for all Enterprise Developer Apps on my iPhone; those of my own and those from other Enterprise Developers. I'm guessing we didn't all forget to update build numbers.

I submitted a Technical Support request through the Member Center. I'm sure there's is a better way to file a report with Apple about this, but that was as close as I found. I've got a screenshot and will forward that when I receive their follow up email.

These problems (A network connection is required to verify ...) seem limited to the east coast.

We were able to trust our app on the West Cost; When we VPNed to make it seem like we were in the east coast, it did not work.

Is working for me now - and but still no word from Apple, though. (And pinging ppq.apple.com is still unresponsive, so I doubt its correlated to the issue.)

Feels like it was an Apple-side network connectivity issue, which probably isn't high on their let-us-know list.

Same problem here with iOS 9.2.1 upgrade I can't install my in-house app, I've already regenerated certificates and provisioning profile but the problem is not solved. Solutions?

Still getting same issue with 9.2.1 also. Stranegly, works ok on iPhone 4 but ot on iPhone 6S - both no same software version???

Hi,

Is this issue resolved yet ?

Hi All,

Is this the issue from Apple ? We are not able to download the inhouse application from our server in 9.0 and later. But it was working fine on upto 8.0. Moreover, i have tried all the approaches like change the bundle identifer in manifest .plist, then made it same as in both .plist and manifest.plist, changed the bundle version, etc. Then tried the same with dropbox concept, its worked fine and can be able to download. Plz Any help can be appreciated.?

Regards

Swam

We have same problem. It appears only after update to 9.2.1

I am also facing same issue.

One year on and I'm experiencing the same problem. Some of our users can tap the itms link and download without issue, others experience a generic "app could not be installed at this time" error message no matter how many times they try. The log files are equally unhelpful in determining the root cause of the problem. Assuming this isn't an iOS bug, more detailed error messages are an absolute necessity.

I have the same problem, I tested a lot of thing to try to find a solution because I have an iPhone 6s that has the problem ...

When i test to "Erase All content and settings", this one solved my problem, but I can not ask my clients to do this ...

....

Nor I! If you can manage to get the phone to produce the error again I would be very interested to hear the steps you took. (And I'd be even more interested to get a response from Apple on this issue after two years of silence. Hello? Hello?!)
