Reply to ppq.apple.com returning 502 Bad Gateway - Unable to verify developer apps on device
Same issue here since this evening (March 10, 2026) on both iPhone and iPad, paid Apple Developer Program account. After extensive troubleshooting — new certificates, new provisioning profiles, device restarts, testing on both Wi-Fi and cellular — I can confirm this is server-side. https://ppq.apple.com is returning 502 Bad Gateway intermittently. It sometimes responds with OK, which makes the issue harder to diagnose as it appears to be working when checked manually. Awaiting a fix from Apple.

Reply to ppq.apple.com returning 502 Bad Gateway - Unable to verify developer apps on device
I've gotten OK, Bad-Gateway, Gateway Time-Out on four different systems. Even when OK is returned, it takes a while to get a response. This started almost exactly at 10am pacific time for me. Like many of you I used the security command line to check my certs, checked my firewall (PFSense), and even switch my build system and my target iPad to use my iPhone personal hot-spot, in order to bypass my infrastructure and still, no-joy. After reading your posts, I have become convinced that this is an Apple services issue, even though their status page says everything is working. More information. I have another project (Project-B) I'm working on, which is being developed on a different machine. Project-B installs on the same target iPad with no issues. I migrated the failing project (Project-A) over to this machine and added the missing certificates to the keychain so that the failing project would build. Even on this second system, I'm consistently getting the error for project-a but not for project-b. S

App installs but won’t launch on iPhone: “profile has not been explicitly trusted by the user” My app builds and installs on a physical iPhone, but it will not launch. Setup: Flutter 3.38.7 Xcode 26.3 iPhone 15 Pro Max iOS 26.3.1 Exact error: ERROR: The application failed to launch. (com.apple.dt.CoreDeviceError error 10002) Unable to launch com.sherpa-map.routestudio because it has an invalid code signature, inadequate entitlements or its profile has not been explicitly trusted by the user. (FBSOpenApplicationErrorDomain error 3) The confusing part is that on the iPhone, Settings > General > VPN & Device Management only shows VPN and Sign in to work or school account, so there is no obvious developer trust option to tap. Is this a current iOS/Xcode issue, or is there a new trust flow for developer-signed apps?

Seeing the same issue here. My app had been working fine for about a month, but suddenly it started showing “Not Verified” and won’t launch anymore. The Verify App option in Settings also doesn’t seem to complete the verification. I’ve already tried several things: rebooting the iPhone reinstalling the app (both latest and older builds) rebuilding and running the app from Xcode trying to sideload via SideStore (but SideStore itself now shows Not Verified) Nothing seems to fix it so far. I also contacted Apple Support and opened a case about this. From what I was told, since this involves developer-signed apps installed via Xcode, it needs to be escalated to the relevant developer/business support team rather than standard troubleshooting. Given that multiple developers seem to be seeing the same behavior at the same time, this might be related to the verification service rather than something specific to the app build. Has anyone found a workaround, or are we waiting for this to be resolved on Apple’

Latest Beta Version Breaks Xcode Testing Builds on Physical devices.
This is a grave issue I am facing while testing my apps on my personal device. This is the error I seem to be getting: The application could not be launched because the Developer App Certificate is not trusted. And on the phone side, this is the message: Unable to Verify App. An internet connection is required to verify the trust of the developer Apple Development... Before I receive any recommendations, such as deleting Xcode or restarting my device, I would like to clarify that I have already taken all necessary precautions. The application I was testing appeared to function correctly in the morning a few hours prior to the update. However, after upgrading to the latest beta builds, iOS 26.4 beta and the latest macOS beta, this issue has become a recurring problem. I would greatly appreciate your assistance in resolving this matter, as it is of utmost importance to me.

Cannot find devices in RemoteImmersiveSpace
Hi, I'm running the Spatial Rendering App sample on a Macbook Pro running 26.4 Beta and the Vision Pro running visionOS 26.3.1. Handoff and SharePlay are on, both devices are on the same Apple ID and network, and SharePlay screen sharing works fine between the two devices. However, when calling openImmersiveSpace, the device picker fails to present and no devices are found. Errors from console: ((processConfiguration != nil && configuration != nil) || (processConfiguration == nil && configuration == nil)) - .../ExtensionKit/Source/HostViewController/Internal/EXHostSessionDriver.m:80: `processConfiguration` and `configuration` must be both non-nil or both nil Unable to obtain a task name port right for pid 638: (os/kern) failure (0x5) Unable to present an ImmersiveSpace for Scene id 'Compositor Services' Is this a known bug or I'm I missing something? Thanks!

Same boat as you... submitted on the 5th of Feb... still 'Waiting for Review' - i've explored every avenue and they're all one-way channels. Phone support are helpless, email support is automated... as are the support responses on here.

Since this evening (March 10, 2026), I'm unable to launch any developer-signed app on my physical device (iPhone 16 Pro Max, iOS 26.4 beta 23E5223k).
