iphone - Unable to download application, <app-name> could not be installed at this time

Question

I am getting this error when trying to install an app to a device. I've been dealing with code signing errors for the last 3 days, and now this.

My app is using a distribution certificate and mobile provisioning profile. It is uploaded to a build server where it is passed as a successful build with no code signing errors. The server generates an application download link which I am using on my device to download the app, where I am getting the error:

Unable to download application, <app-name> could not be installed at this time

• My app is using a valid distribution certificate
• My app is using a valid distribution provisioning profile
• The build server passed the app with no code signing errors

From what I understand, the app should be able to run on any device as it is using the distribution certificate and profile. Other apps that I've worked on work fine with this method. Does anyone have a clue why my app can't be installed?

Most common causes of this issue:

• Device storage is full
• The provisioning profile is a developer provisioning profile
• The ad hoc distribution provisioning profile is corrupted and the device is having an issue with it.
• The device was restored from a backup and is causing a conflict for over-the-air distribution
• There was a network timeout
• Architecture settings of the build and the device are incompatible ( can sometimes happen when "Build Active Architecture Only" is on when building).
• Not Using Mobile Safari.

To find out the exact cause of this issue:

• Connect the device with iMac.
• Open Organizer then choose devices.
• Choose your Connected device from sidebar.
• Choose Console inside the chosen device.
• Now install the app it will show the exact cause of problem
