ppq.apple.com returning 502 Bad Gateway - Unable to verify developer apps on device

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). The error is:

"Unable to launch [app] because it has an invalid code signature, inadequate entitlements or its profile has not been explicitly trusted by the user."

On the device itself, it shows: "Unable to Verify App - An internet connection is required to verify the trust of the developer."

What I've tried:

  • Created a new Apple Development certificate
  • Deleted and reinstalled the app
  • Restarted the device
  • Tested on both Wi-Fi and cellular
  • Confirmed Developer Mode is enabled
  • Removed all third-party CA certificates from the device
  • Verified the code signature is valid (codesign -dv shows correct Authority chain)

The root cause:
https://ppq.apple.com is currently returning 502 Bad Gateway. I confirmed this both from my Mac (curl -s -o /dev/null -w "%{http_code}" https://ppq.apple.com → 502) and from Safari on the device.

This affects all developer-signed apps, not just a specific project.

Is anyone else experiencing this? Is there an ETA for the fix?

Environment:

  • Xcode 26.3 (17C519)
  • macOS 26.3.1 (25D2128)
  • iPhone 16 Pro Max, iOS 26.4 (23E5223k)

My app just verified without issue, so hopefully this is close to being resolved.

For those who haven't tested, we are seeing this resolved on our end!

System status reports resolved as well.

Looks to be resolved for me. App is now verified.

appears to work now. thank you guys.

It works now. We're back.

Same here

Seems to be resolved now 🙌

This has been fixed now and received updates from Apple as well on the same on one of our calls we were on with Apple Engineering team.

And we're back. Thanks a million!

Yes, I've been having this problem for about 5 hours. I've checked my certificates, turned all of my devices off, reset network settings, and had given up trying until i saw here just now that it has been resolved. Great post.

Fixed now guys

Following this thread. we were having issues with Apples as well not opening. Also experienced some apps disappearing and then repushing back to our devices. We use an MDM and all of our devices are ADE. We escalated this with our MDM support and they referenced this posting.

Thank god everyone has the same problem! For the first time I’m happy for a problem being common for everyone 😅 Man i have literally reset all my devices.
