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)

Ugh I hate this, tho I guess its ok I’m not the only one. I hope apple will move on this quickly.

oh nooooo I just spent the past few hours troubleshooting this from so many angles... even wiped my phone + MacBook 😑 still not luck as of 2:18pm PT btw.

I've been trying for an hour, I thought I had destroyed something, then it occurred to me to check here.. On developer system status everything looks fine

I spent an hour with Apple Support and it seems they're not aware of the issue. Please reachout to apple developer support so they get higher priority to resolve this. It can be done through developer apple site: developer.apple.com / contact / topic / select

I have the same problem, I can install my app in my physical Iphone. I'm getting the message an Internet conection is requiered, but I have Internet conecction.

Boost the topic if you haven't already.

I'm having the same problem. It worked on my test iPhone until 7 PM UTC, but now it only works on the emulator.

Same with me starting with 03/9 right after update to 26.3.1

Same!

After 4-5 PM CET it has stopped working :(

Getting the same issue !

Also having this issue as of 10am PST. Tried everything in the OP. Hope this is resolved soon because it's completely blocking my work. Also, this kind of thing should be shown on the status page...

Same - just here to push the thread in order to get more attention to the problem..

Same issue. Driving me mad until Claude pointed me here.
